I just got a MacCat deluxe, only had it over the BB. I had side pull outs added to my deluxe for when i use the bridge.
When i was looking, before i got the deluxe, i vaguely remember reading somewhere that as long as the ridge is 10ft that you should be fine, depending on how much coverage you want.
Experts are the ones who think they know everything. Geniuses are the ones who know they don't.
Gather round your hearts the tinder,
lay the oak and pine together,
kindle all that is within you with a warm and cheerful spirit.
