I use a supermarket shopping basket with tie wraps inserted in the bottom. It was cheap full of holes and not that heavy. I use a rubber Occy Strap to hang it round my waist.
If you look at the numbers you don't really need long running line lengths unless you are casting well over 120 feet. Of course it depends on head length but a standard set up, like you would use on a 9 footer, 10' leader, 30 foot head and 80 feet of running line will get you near 120 feet all of the time.
If you use a longer head, say 45 feet, 9 feet leader , is 54 feet and 80 feet of running line is 134 feet. What this really means that a standard basket that you would use on a 9 footer is quite OK.
The beauty of DH rods in overhead mode is that 100 feet of cast is easy, fast and requires very little effort and that 100 feet is about as far as experts cast 9 footers, others rarely get past 80 feet with a tail wind.
If you give me an Email I'll pass on some running line info.
I am in a running war on DH rods over here, look at
www.flylife.com.au in the forum tackle double handers. Pretty interesting, might need some REAL long rod floggers like Bob Meiser to liven things up a touch. Some interesting posts.
A stuffed running line, 50lb Bionic Braid, or any 40/50lb GsP braid without funny coatings, like Gudebrod SST in 44lb stuffed inside 20lb Gudebrod braided mono, measures 0.021 or there abouts. Very hard to measure without compressing the line. It goes very well particularly if you polish it with a good furniture polish, like Mr Sheen. If you have that in the USA.
But I now have a Oz DH rod, a 12' Talon WMD (weapon of mass destruction, vbg) in 7/8. First cast out the front 100 feet without fuss. Head 30 feet 9 foot leader 80 feet of Talon running line 0.021. Was great stuff. Not terribly expensive either. Had it all on a Old Florida LA88 reel. Very nice gear.
My current tally is a 15ft 10/11 USA Talon Madgar, a 12' 4" Loop Blackline in 8/9 and a TFO 12x12 Lefty TiCr plus the 12 foot WMD.
Latest thing in running lines, like Max stuffed is 80lb Power Pro hollow GsP braid, I actually used 120lb, stuffed with 10lb mono. It goes like a rocket is very thin, slick as KY jelly and doesn't get knotted twisted or looped. Very nice stuff and it also measures around that 0.022" figure
I have recently, last 2 months had both lenses replaced in my eyes. Now I can actually see things around me without distortion. So its back to fishing again. Chers have fun Max
Ps must be getting over winter over there, here summer hot very, windy no rain dry as a million year bone.
