tape your inserts not your tires?

[rootar]

I talking to the hobby shop about which of the molded foam insert to get for my new SUT's standard bowties and he swears up and down that it works great to do a loose double wrap around the foam or molded insert and then put that in the tire instead of taping the tire, swears its less likely to come apart on you and works the exact same, i did watch his truggy run and could tell his tires were taped but he corrected me and said it was the foams, has anyone else seen this i thought everyone turned the tires inside out and actually taped the tires?????
