I've used Sufix Invisiline and Seaguar Invizx and the Sufix is fine, but does require line conditioner whereas the Invizx does not. The invizx does have a bit of stretch as far as fluoro goes, but it's sensitivity is unmatched. If you have ANY presentations that fall on slack line, I would shy away from braid for those purposes, but that is just my opinion. I have felt bites with fluoro while picking out a backlash, but braid requires you to watch the line intensely.
