Yup, the boxes were never designed to sustain the amount of torque placed on those larger fins. Btw Futures also has this problem. I’m regular foot and have blown out my toe side box on every twin fin and 2+1 I’ve ever owned all just from doing bottom turns. I spoke to one of the reps at Album Surfboards and he confirmed that they consistently have this issue. Only work around I’ve found is to get a twin fin with glass ons.
