Hey Dan...
I know what you are talking about with no (or little) vertical when using a plane/motor combo that everyone else said is so hot...I'm across the mountain from you in Alamogordo...we're a little over 4300'... and it takes a little bit more motor and a little less prop the higher up you get. I have a Somethin' Extra with a Saito 72, running an APC 13x6 prop. Everyone says this combo should should be the hot ticket for vertical stuff, but I barely have enough thrust to hover. Just thought I would throw in my 2 cents on this thread...I'm about to try out a WM 46 size Cap 232...and first flights will be with VERY little throws...I learned that lesson from the SE...
