I have had issues with braid wind=knotting up here as well so have reverted to the old stand-by of using Fireline. Problem solved. So, for me, I would look at getting that although Fireline is pretty thick, not nearly as thin as normal Braid.

Ditto above re braid,I use ultra PE8 its 113lb  and the PE 5 was rated to 78lb  maybe I got the "special stuff" along with Kev and Jas

I used to have issues with wind knots casting Suffix performance, I don't think it is a true 8 carrier dyneema weave braid, and is not the best casting string on the market. I posted up here about it and put a lot of advice into practice from members here, and I stopped getting wind knots; quality supple leader, playing around with leader length, ensuring tight line wraps on the sweep and wind motion, changing the distance the lure hangs from the rod tip when casting etc. etc. but probably most importantly to keep the focus and engagement in what you are doing throughout the process, even when there is visuals of biguns frothing the surface behind the lure and following under boat, that is; keeping the anxiety in check.

I dunno about that fireline Phil, it's the ultimate light string for light tackle work, especially this new fireline exceed, but more a kin to stiff rope over 20lb, but then again that's just from me fondeling it in the shop, experience would talk more sense.

Easiest thing to try is shortening the leader. Nice and simple.
