RE: gst durabillity
I do not own an MGT but i hear good things about them. Seems like quite a few guys like them.
I personally own a GST 7.7 and it is TOUGH, put it this way it's tougher then my Savage SS 4.6 and the Savage is TOUGH as nails.
Just looking at the trucks and the specs i would get a GST 7.7 before i got a MGT. 5HP, 3 speed tranny w/reverse and it's HUGE!
Thats just my opinion
