Tom you are pretty much on the money. I ran my DLE55 with a MTW75 canister and a Falcon 23X9 and it was a great combo. The Mezj 23X8 will be a tad more load due to thicker blades and will be about ideal on the 55. A larger dia and less pitch can slow the airplane down but will make more prop noise. The trick here is throttle management. This will require both set up of a throttle curve and pilot training.
