Tex, how do you eat a cow....One bite at a time? 

Tex, how do you eat a cow....One bite at a time?    Maybe you can eat a 100 ft tree in a couple of cuts?  The AR60 lift (fully extended) and AR 120 (fully extended) were roughly the same according to the doc.  In air weight, whatever that is, is much greater (2x) on the 120.  The SR60, whatever that is, is the one you referenced @ 100K.  I don't think that was what was on the lake in Brazil....

I don't know about all those numbers, but I remember the AR60 was handling 40-50 ft logs fine, so worse case that would be two cuts with the AR120 sitting in the same spot....
