Trying to size a frame for my first 29er ..I know I am being an idiot here but..

Based on the geometry linked to above, I am looking at the small 15'' .. while I am 6'1 with a 78'' wingspan and a 32'' inseam...

As it stands, the 15'' frame produces, for me, a manageable standover, the wheelbase would be a half inch longer than that of my 19'' beone 26er, and (adding an inch to the center to center top tube measurement to yield the ett) the ett is virtually the same as my beone, which fits me well.

I have heard that one should go down one size moving from a 26er to a 29er, but is going from a 19'' 26er to a 15'' 29er an ignorant move?

Dude you're at least a large. look at your top tube lengths and standover as compared to a 26" bike. A small wont work!

Yeah =) , I knew i was being an idiot
I was measuring standover to the lowest point on my bike
should of known that it was measured to the center of the top tube on the geo chart
