BananaasQ, do you mind if I ask what type of fishing you are doing with this flouro?
My honest opinion. If you are fly fishing still waters (Lakes) for picky trout, yes I do believe flouro can make a diff. I buy the wee spools of seaguar in 4lb which I use most of the time, and the odd time if the lake is known for hogs I'll step it up to 6lb.
However in the river? I went through a flouro stage years back. I tried Seaguar, Suffix, Maxima, and others. Cost me a lot of $! For me the experience was terrible. I busted off a lot of nice fish right at the swivel knot. I even switched from the improved clinch to the palomar knot (supposedly the best knot for flouro) and still busted off a lot of fish. And I didn't find I was hooking up any more than my buddies with mono leaders.
This being said, I fish with a few guys who only fish flouro leader in the river and they swear by it. So, fish what you like and what works for you and what you have confidence in!
I would recommend if you want to try out some flouro don't cheap out, and don't go out and buy several big expensive spools in case you don't like it. I would buy a small spool of Seaguar Blue Label (seems to be arguably the best) in 15 or 12lb and try it out for a season. If you can land springs, chum and coho on it then it has passed the test!!!
Personally I gave all my flouro away with the exception of the stuff for lakes. I now stick to Maxima Ultragreen mono leaders in 6lb-15lb for all my river fishing. This is what works well for me and what I have confidence in.
