hope you're patient, 'cause this thread is mostly a dead horse. It's actually less than a 0.4" difference on the TT,but not really the point. My experience has zero bearing on anyone else's WRT fit. I think you'll probably come up with what I came up with: that after you measure your other bikes & look at the geometry tables you will know what size you need. Best bet would be to find one local to you & check it out...if that's possible.
