Aside from refering to manufacturers websites for line reccomendations,are there any general rules of thumb when it comes to choosing a properly matched line to any given rod?
First of all,let me just back up for a minute with a bit of background about myself:
I've been avidly fishing single handers for close to 25 years now,but I am a complete novice to this two-handed casting game.I've had an interest in switch and spey rods and have been lurking around the Speypages for a cpl years now,but only just recently purchased my first "new to me" complete two-hander outfit from a local flyfishing forum classified.What I have is an 11'6" Beulah 6/7 Classic Spey rod,that came with an Amundson 9/10 reel,Airflo running line,Airflo compact Skagit 420,and Airflo compact Scandi 420.Now I had assumed this was a well matched,balanced outfit,but since buying it and having spoken with a cpl of very experienced speycasters,both in person and on another cpl of FF forums that i frequent,both of them suggested that the Skagit line is likely a good match for this rod,but I'm way too heavy on the Scandi and should be looking for a Scandi line closer to 360gr,maybe even 330 or 390?
So that said,my question is....is there a rule of thumb or formula of sorts for choosing different styles of lines to match a given rod?For instance,assuming the 420 Skagit is indeed ideal for my 6/7 weight rod,does that mean i should be looking for 60-70grs/stated rod weight in a compact Skagit?Likewise,if a 360gr Scandi is what i need,can I assume that means 50-60grs X 6/7 is correct for a Scandi line?
Also.....could I theoretically apply these formulae to matching lines to rods should I.....OK.....when I inevitably buy future two-handers.....cuz as you all know,this shiite is addictive.
For instance,if I were to buy a 9/10 rod and wanted to line it with a Scandi,would I use 50-60grs as a guideline and be looking for a 500-540 gr Scandi line,or maybe a 600-630 Skagit?
Also,would a longer rod,say a 14' 6/7 for instance,change the equation any/not at all/significantly?
Now I'm sure I could always just refer to mfr reccomendations in the future,but i'm the type of person that always has to question and know the "why" in everything like this,whether it's arrow spines or powder charges or whatever...why this line weight and not that one?That,and I hope that sometime in the distant future I'll know enough about spey casting that when some newb shows me his new rod,i'll be able to make a line reccomendation to him based on personal knowledge in regards to the science and physics of the sport and not by simply googling it or going by what some spey line R&D guy figured out on his own and reccomends.
