I sincerely wish I could.
I fear that you think we're trying to simply pass the Kool-Aid from the racing community that you NEED a 22" hauler style tire for all applications. That's not it at all. This is based on my own, people I ride with, and others who ride similar stuff experiences.
Walden and Oregon are the only two locations I know of with a significant amount of treeshoots. I have allot of experience at the former, and I asked Seg to chime in because he has allot of experience at the latter.
Treeshooting is a blast! And I have no doubts that you guys would LOVE doing it. (4gunz is hooked for life after 1 trip to an 800 acre sandbox LOL).
But there is also a different set of requirements than normal duning. Deep sand ruts, from other quads that hit the shoot before you, can hang you up on the skid plate taking all or just enough weight on your tires to cause you to trench in. So a taller tire (without getting crazy) will help you because the distance between bottom of the skid plate to the sand will be more when you're in those ruts. Also, as you both explained momentum is key....in treeshoots you don't always have that option (damn trees LOL) 120 degree or greater turns in the shoot now wider than the quad are not uncommon, so you have to be able to get traction and regain the MO you can at each corner exist to ascend the climb.
We also have what I call "roach motel shoots" because you may check in, but may never check out
These shoots have one entrance, and no other exist. if it's too much for your setup....you're stuck and nothing out there will "pull" you out besides maybe a truck and a LONG ASS winch. 4gunz found one of these last time he was in Walden and ended up walking for a mile to find us in the dark.....in Cougar heaven
(it took preddy, Troy, Gunz, and I ~ an hour to get him out
)The problem is that you can't tell how nasty they are till you in it because of the trees and foliage shrouding the lower parts of the shoot from the top....again a tall tire will give you a better chance of avoiding this.
I have some 20" stars that I will ask to put on someone's 3 mod at Walden and take some pics and video so you can see what I mean.
