I have definitely had tip dive issues on a pair of 180's mounted +1.
Have another pair that never really got ridden this year mounted with demo bindings. Rode them 1/2 day in super deep and them tips were diving, but it was about 2-3 feet of fresh so most tips would. That being said BillH's EHP's weren't diving. I had them -1 probably before we called it a day.
I think the tips of the Pow +'s being so stiff, can be difficult getting them them not dive...
Oh yeah, I'm 5'9" and about 165ish.
He who has the most fun wins!
