I think normally the 210 can would suffice … but depends on your style of playing and loudness of fellow band members
Last week my RM800 using two 210 cabs was buried at an audition with very loud hitting drummer and Marshall 4x12 guitarist
I felt then my rig was under powered but of course it’s not !
Buying again however I would get the biggest and highest wattage second hand cab you can find, may even be a heavy beast but it will have a full sound .. TE, Peavey, Laney etc do fair priced heavyweights
