I spent some time looking into this, I can really only speak for Fishers because that what the shop I work at carries. I was debating between a new 26 inch rider and a 29/ I am just over 5' 10" and normally ride a 17 1/2 inch frame, and was paranoid that a 29 would have too much standover height. Pulled one out of the rack rode it around the store, and the around the yard and the parking lot bike felt fine. Went back into the shop and strted crunching the numbers and found that the stand over height on a 26" fisher and a 29 inch fisher was a little less then a 1/2 inc different. Moral of the story.....ordering a Paragon.
Oh yea no overlap
