My M&M cruiser is 8" at the front so my 33 ACE work well, but it tapers down to 7.5 at the back (it is called a banana board for good reason) and my wheels stick out, but it doesn't effect the way it skates or bother me that much, plus I am not buying two sets of trucks for a cruiser.
Pabst - Gonz has always taken the "rules" of skateboarding and turned them upside down, that dude could skate a board set up side down and do shit that most of us would never even think of.
