Last month I did my own test of all 3 @ 60lbs. The Switchback and Trykon were very close in feel. I got upper 270's lower 280's every shot with them. The Bowtech I didn't care for. It was fast, but actually kicked a little in my hand. That one hit mid 280's.
My test meant nothing, b/c I took the $ I got from my Outback and put that towards my Starcraft I bought. It's fishing time...I'll get a bow later this summer.
