Welcome aboard! I agree with @LCG, you seem to have some choices
laid out. I don't have experience with either, so no help there. I can also
recommend BPS Carbonlites. I have earlier versions but would have no
problems recommending the 2.0 as they've maintained their reptutation.
As for braid, 10# is fine. I use 10 and 15# Power Pro and Super Slick 8.
Leaders are your choice. I'll go down to 4 and up to 15, but tend to go
with 6, 8, 10 pound tests on average.
The FL is getting solid reviews. I love my CI4+ 1000 (I use 1000 size
for all my bass fishing). Tackle Advisors absolutely loves the new FL....
