concerning the Hoss, don't know much about it. I weighed well OVER 300 lbs for a few years. I'd ride a Jamis from time to time, seemed fine. Honest, i don't think you'd brake ANY o' those you stated NOR would you brake the specialized. You stated price though. Jamis are less money ALL 3 models of thier comms...others as well. Hey if your LBS stock's those you mentioned ..why not..YOU asked for it though. I'll add : Bianchi makes a STEEL comm. bike..now THAT is SURE to be fine..seen it..haven't riden it. Just an extra idea. I realize that finding some brands in some areas are difficult. Cruisers are generally heavy..NOT heavy-duty as one might suppose though, you busted an inferior bike. When I was 340..I rode steel hybrids no-problem !
