Ive got the 2 blade Safari on my Tour 82 for summer months in grass and pads. Works fine, but will vibrate a little more than the 3 blade prop.You can also adapt an MK prop to fit an MG very easily. Just have to use a Dremel tool and make the pin slot slightly longer. As for MG or MK, Ive had both. Didnt find one any quieter than the other. I prefer the MG for the (much) lower profile, the SS shaft, the mount, and the feel of the metal pedal. The only improvement Ive made has been to replace the pull rope with an MK rope with the rub guard (Mr. Jones recommendation). I plan to add the lift assist cylinders in the near future. Other than that its just fine.
