I love sunline sniper. It's the main Floro I use. First off you will notice it cast better than any Floro Out there. The big thing here is compare line diameters not pound test. Compared to seagur it is weaker & thinner in the same box labeled pound test.
20 sniper = 17 seagur
16 sniper = 15 seagur
12 sniper = 10 seagur
Hopefully this will help you pick the right lbs test. When big $ is on the line I spool up with sunline.
This is what I have found to. had some 20lb and was disappointed in it compared to seguar, the line casted way better and lasted longer but I broke off some fish. Going to try the 25lb and see how it works compared to 20lb seguar. The 16 sniper is pretty sweet and i have had good success with the 12lb reaction floro
