I've spent several years with two-handers in overhead situations but these are primarily surf situations. I have also cast overhead on steelhead rivers with my two-hander but I did so occasionally to reach lies out of range for my spey casts as I was becoming a better spey caster. I find myself rarely if ever going to the overhead in recent years, but not because my spey casting has gotten so good that I can reach equal distance (spey vs. overhead) by any means. I just think I am happier spey casting
But let's talk about overhead casting and lines, a favorite subject for me in surf situations, rips, and wind. FWIW, my observations are as follows:
Long Line Advantages:
- provide continual feedback to the caster when overheading so tend to be easier for people to cast than shooting heads for distance
- allows caster to aerialize a long line, making casting feel more relaxed and familiar
- dramatically improved line control in currents, roll casting, re-casting to moving fish, etc.
- high grains/energy can push very large flies
Disadvantages:
- strip retrieving the fly close to you requires a troublesome roll-out of that fat line for the next cast
- loading the rod requires a lot of line in the air due to distribution of grains over such a long taper
- requires huge reel capacity, reduced backing, and considerations for weight balance with rod
- hard to find in anything other than floating
- expensive
I could imagine making soft casts to tarpon with a long line, a short strip sequence with a pick up and laydown 20 feet further to the right, etc. I can imagine working a flatwing in a longshore current, using spey motions to set up for the next cast in the surf. There is a place and time for it, no doubt - but with all due respect it is not my idea of the perfect line for the coast.
There are also shooting heads, aggressive head/taper designs and specialized lines for two-handed overhead casting.
Shooting heads: compact, high-grain heads on thin shooting lines made specifically for distance.
Shooting head Advantages:
- usually the most consistent distance line for the practiced caster
- able to handle harsh wind conditions
- allows the fly to be stripped very close to shore where many gamefish eat
- minimizes the time it takes to get the fly in the water, often one backcast with no falsecasts
- high grains/energy can push very large flies
- easy change-over from sinking to intermediate to floating using loop connection
- uses your existing reels, no over-size requirement like long belly lines
- inexpensive and comes in all densities
Disadvantages:
- rod motion must be very crisp and true to get good casts, not a lot of feedback - will not tolerate casting faults
- can not aerialize more than head plus a few feet or else hinging gets bad
- loop to loop connection must be minimalized to prevent hitting guides and fingers
- shooting lines can be stretchy (look for low stretch)
- shooting lines can be abrasive (braid for instance)
- shooting lines can be thin and blow around, tangle if too thin
- it may take a while to figure out what heads work best for the rod and your casting
Specialized lines - just as long belly lines are specialized for spey casting, some line designs are excellent for overhead two-handed casting. The Rio Scandinavian heads are designed to be double-duty. Wulff's triangle taper saltwater lines are actually specialized tarpon lines and have a very well-behaved short continual taper (30') that is great for two-handed overhead casting (but only the floating comes with a color change at the head). Most exciting are the new lines coming from Airflo, made specifically with the two-handed caster in mind... 150ft long, 30foot head, color change, sinking or intermediate clear heads with skyblue running lines and a taper that is designed to hold on to the loop for greater distances, e.g. the "Forty-Plus" taper.
Preferences FWIW:
If demonstration casting I'd use a short spey line like the Hardy Mach I 10/11, Rio Windcutter, SA short spey, etc (overhead casting on a two-hander). Clean long 'pretty' loops, also spey casting.
But for fishing surf with shooting heads I like the 35-45 foot headlengths like the Airflo and Rio heads with running line either a 50# Rio Slickshooter (amazingly smooth shooting, good in the hands but a little stretchy) or Airflo Miracle Braid (almost no stretch but a bit abrasive). Some of the other lines feel better in the hands but blow around too much in the basket and tangle or get blown out into the waves. You could combat this with better basket designs but the slickshooter and miracle braid fare very well in this respect with common line baskets on the market today. Wulff's 30ft heads don't come in grains high enough to load most two-handers so the only alternative is to cut the head off their full line$ to make a shooting head, which is not economical. Super turnover on the triangle tarpon taper though.
I am very excited about Airflo's soon to be released two-hander lines, specifically made for two-handed surf fishing. At 150ft long with a compact 30ft long cast taper in clear intermediate and fast sinking with intermediate skyblue running line, these lines challenge the caster to hit the backing knot, which is childsplay with standard 100' flylines.
