    if they want to share the info that's on them basically its a pros con's thing between the 2 but from what I gather the H1 is better in most ways but not in some ways if that makes sense

    Its not a secret Ale. I asked a friend a while back what his thoughts on an H1 wheel in comparing it to the 15.5 wheel. Below is what I info I have:

    One thing you need to take into consideration when talking about the larger wheels is that the weather has even more of an effect on your boost than the smaller wheels. I have a buddy who just put in an et24 wheels and lost 4 lbs of boost from one week to the other. With the h1 in temps between 85-90 you will see 17.5-18 psi boost at 8550 and 19lbs at 8850, and 20 at 9000-9100. In temps in the 60's, I have seen 20 at 8650-8750 and 21 at 9000+. I think at 9150 you can get 22 in cool weather. When you have a wheel like the h1, you really need to take it easy with holeshots because you can burn through a clutch really quickly. Also make sure that if you ever get unhooked to take finger off throttle before landing to protect clutch as well. Even though I have a wicked holeshot, I really don't do it because of this. If you went to an H1, you will definitely meet the goals listed above, however in my opinion you are not too far off in terms of boost and speed. You will get some more performance with the H1, but with all the changes you will have to make to support it, is it worth it? The setup you have right now is kind of the best of both worlds with a little more room to beat on your ski than mine. My setup requires a little more babying of the ski to maintain reliability. For me this is not an issue because I'm cruising most of the time with the occasional pull of the throttle, but I know you guys like to ride hard.
