You know BTM, I looked at the 72 and the 91. There were only 2oz difference in weight and I thought I had more use for the 91 post Pizazz, so what the heck . In the end, @5200', the 91 is not that bad as far as too much power. I always thought that that is what the throttle stick is for anyway...... and I would do the same again I think.
