I'm going to try an 18x6 to be certain, and I've also heard of an 18x5 that would probably be better, although I've not yet seen one for sale. When I get my wife out to the field and get some video, I'll send it to you to convert for sure. I appreciate the offer. I'm be sure to include some "good" stuff, but it could take a while. My wif'es not the die-hard I am and it's still pretty cold up here in the high desert.

The 6000' gives about a 20% decrease in power on any given engine. It's a rule of thumb the guys seem to use around here and from my experience isn't far off.
