We've had a lot of crops from the 6x6, but personally, nearly all of mine have been 6x6 uncropped. If it's centred it usually looks okay. My last one wasn't centred at all, but I think it still looked alright. Sometimes it looks okay if you do the old "French mount". I have a 4 blade easel and that helps a lot with this, even though I don't really know how to use it properly yet.
