Probably depends on which type of bait. I’m doing pullbaits so they can be pretty firm. Swimbaits start to suck if u get them too stiff. At least that’s what I’ve noticed. I ordered lure raft hybrid between saltwater and regular, it was wayyyy to soft. Not even close to the hardness of the regular alumisol. I just called alimisol and got them to send me more in bulk, rather than burn money experimenting.
