I use both. Nylon Vater Manhattan 7A on my E-drums and Bopworks Birdland model on acoustics. I've used the nylon on acoustics too and have never had a problem with them breaking or ruining heads, etc. That has to do with striking the drum incorrectly, IMO, not the stick tips. The nylon are not great for jazz--the Bopworks sound great on my Bosphorus.
