I normally fish the 16 lb Sunline SX1 braid on my spinning reels, only reason I fish 16 lb is because it is that optic yellow color and I really like that and unless they have just started making it in 20 lb, then 16 is the highest the yellow comes in. Have tied everything on it from 6 lb floro to 20 pound floro they will both work just fine, just be very careful with your connection knots. I use the uni to uni knot and always tie it the same way. I always tie the braid part first and tighten it down just before the knot would be considered tied. Then I tie the floro side and only tie it to the point that it starts to tangle in the braid. I then wet both knots really well, and pull them together. You need to keep some tension on the tag end of the floro ( I use my teeth) as you pull them together, then as the knots touch, pull on the floro end some to tighten up more then the braid tag, then finally pull the knots tight together and you are done. Might be more info than you wanted, but I have had no issues with the uni knot and use it on other baits as well. It is a great floro knot in my opinion.
