Grips

I ordered my 913fd with a  golf pride whiteout grip standard size.  It felt and looked bigger than my driver shaft (same shaft)  I cut off the fairway shaft grip, and there was 2 wraps of tape.  I also got a set of 712mb's a few weeks back with the same grips.  Some of them have 1 wrap and some have 2 wraps (I haven't cut any of those off yet, but you can see and feel some are bigger than others) and some of the grips aren't even on straight.  Any reason why that would be?  You would think if you ordered clubs without specifying extra wraps of tape they would come with 1?  Or do you have to specify 1 wrap of tape only?

Thanks
