It happens on some reels whether you use a Bionic finger or not.
On my most recent trip, it started happening with my Ultegra 5500. Cast 2 brand new perfectly made traces into oblivion, one after the other...
Was so annoyed, I spent an afternoon opening up all my grinders and removing every single Bail trip lever out of all my reels. No more snap offs mid cast. Stradic, Sustain, Aerlex, Sedona, Ultegra, Exceler... the only one that didn't have a Bail trip lever was the Bullseye!
Made it so that I don't have to rely on my memory (to turn the spool round) anymore. Now it's Reefman proof.
