That or the 1520. Pretty sure the 1717 are on sale still, so you cannot go wrong with the price. I have run the 1717 and a 1521 neu and they both rock. You will want to dial down the power on the 1717, but the MMM has plenty of adjustability so you will be good to go.
linc do you still have any motors for sale? the 1521's or a cc or anything else? Im about to pull the trigger on a new motor but I figured Id ask you first! peace
