Yeah, that makes sense. I'm quite a small guy which puts me off but casters+bandmates=pieceofpiss!
I'm really smitten with the one I've tried out which was a 70's silverface with customized speakers. I'd like to look at a newer one with an effects loop so that you can put delay after the vibrato etc. Maybe a mod job could be done on an older model? I don't think the newer ones would sound as sweet, or look as charming.
In my opinion the reissues are better than the '70s ones. I tried about three silverface '70s Twins before testing out the RI, and although they're really not much different at all, the RI seemed more solid, and sounded more full, in my opinion. The RI is more money, but for me it was worth it.
