MT vs Airmaster on 915iS

[flyboy72]

I have just placed an order for a SuperSport 7 with the 915iS engine. I need some input on the pros and cons of the MT propeller with or without the prop lever, and the pros and cons of the Airmaster prop. I currently fly a Cirrus so I haven't had the blue knob for 20 years now, but I'm not opposed to the blue know either. I understand the MT is a more expensive prop than the Air master with its 4 preset settings.

I appreciate all your input.

Thanks

Weight is the main problem with any constant speed prop on a light aircraft. No doubt MT makes a great prop. Airmaster does too. I went with the Airmaster due to price and weight difference, not because I thought it was a better prop, and I still had to add 15 lbs on the rear of the plane.
I think there was a 14 lb weight difference in the two props mainly because of the governer the mt has to have mounted on the gearbox.

Which prop was heavier? It looks like the MT is heavier but want to clarify.

How/where did you add 15th on the rear of the plane?

MT is heaver, 15lbs by the tail wheel. My plane was still within cg but it flys much better with the weight.
