If i have learned anything in the past, then its never to use a softcase... It just does not protect your expensive gear well enough.
Especially if you go for a case with wheels, the extra weight of a good hardcase is not to bad. The protection it offers is worth the extra weight in gold..
Bachus do you play out professionally?..That is a total myth,...
I have NEVER used a case with wheels who wants that weight...and what about all the other gear speakers, stands etc etc ?
any pro player gigging should use a Rock & Roller multicart...
