I have placed my order on the Holeshot-Corbin a few days ago.
This seat is not a re-badged version of the Corbin design. It is true that, just like the Corbin seat, the Holeshot unit is about 3/4" lower than the Wee OEM seat, but it is also narrower (at the front) than both the stock seat and the Corbin design. The end result is, folks that are short on inseam (like me) should be able to reach the ground a little easier without resorting to installing longer dog bones.
Yes, it is way more expensive getting a Holeshot seat versus a pair of dog bones but you can achieve the following benefits:
(1) A more comfortable seat for all day touring (I personally like a firm seat),
(2) You can reach the ground a little better,
(3) Underside and peg clearance should not be an issue.
However, if you just need that extra half an inch to reach the ground comfortably, you can try shaving the rubber pads at the bottom of the stock seat to (no more than) half their original height. This should lowering the stock seat height by about 1/2". It may be worth a try as it cost you nothing!
I would only resort to the dog bone option for lowering the seat only if the Holeshot seat could not give me the confidence level I want to feel firmly planted on the ground. That is, if my heels are still way off the ground with the Holeshot seat installed and rear pre-loading at its lowest (this is the setting for my 133-lb. frame). I will find out in a few weeks, 'cause there is still snow on the ground and everything is frozen solid in the Great White North!
