INT certainly seem to have dropped the ball on the marketing front during this softy craze. I believe they have a lot of contracts with lifeguard associations and surf schools, around SD at least. The plastic bottoms develop horizontal cracks fairly easily
FWIW, I have a 5’4 r-series from Almond that is pretty fun. It made of denser foam (like a cooler) so it’s more rigid and surfs better that the soft foamies. However it dents easily- like a foam cooler would. So now I’ve got some accidental “channels” in random spots. Kinda defeats the purpose if you have to baby it more than a hard board. But I can still keep it in the suv for surf emergencies or drag it to the beach with all the kids’ toys for family beach days. And those are the 2 reasons I justify it to myself.
