A problem that has developed with my 8" swimbaits is when I catch 20+ pound fish the rear fin breaks about 80% of the time. I am currently using a relatively rigid thermoplastic and have not yet tried other, more flexible plastics yet. For those using Lexan, do you observe this phenomenon? From my research, the vast majority of the strikes come at the rear 1/3 of the baitfish and I'm suspecting the more powerful jaws of a larger fish is too much for my set-up. My plastic thickness is about 3/32" which gives the best optical properties. I was hoping to avoid going thicker.
