I think that is a matter of opinion on who is using them. I have one of the Dels stick molds that I really like, some people don't like them and prefer Bears or K Molds instead. I see nothing wrong with the mold I have and the fish don't seem to care either. Its a matter of trail and error. I did notice that in hand pouring stick molds you will see occasional dents but you can avoid them by learning what causes them. It took me about a week to pour with out getting any voids/dents and I did some searching on all the plastic making websites. I even made a 6 cavity stick mold out of fiber glass resin that makes great baits. Good luck with your lure making and have fun. Don't be afraid to experiment, after all its just plastic and you can always remelt it.
