I am thinking about changing the backing on my reel for something thinner and stronger like gel spun line (I'm currently using 20lb Dacron). The goal is to fit enough backing into the reel for Atlantic salmon fishing.
The reason is that I bought a new fly line that is both longer and thicker than the previous one, which was a sinking tip one. Now I can't fit the previous 200 yd of backing that I had.
I know that the answer is to buy a larger reel, but before that I would like to try some alternatives. I have heard that there is gel spun and that some people use fireline as well, but will these work well? Will the attach well to the reel spool? Won't they damage the fly line where it is attached to them? Will I risk cutting my fingers?
