I'm done building on 600's and Sevens,after the Montucky hit the scene. Also due to the Ti takeoff,one can get a 700 build light and right,for modest loot,if inclined.
Hint..............
I've done the Ti / 700 light thing, and it turned out right. Haven't done the Montucky thing yet....but you know how it is, you were a wayward youth once, too....
