I do not notice any unusual vibration, but you are right that I don't have another Skymaster to compare against.
I am pretty convinced that I need to balance or replace the prop, and was literally near top of my sun n fun shopping list...to likely get the MT props. I say top because I am thinking I might upgrade the engines in the BumbleBee or build a twin velocity...want to go faster. So when I evaluate the 3-bladed MT props, I will need to understand (with that big of cost) whether they will work on a bigger engine in the T337C, or just the TSIO360s.
as for composites from Owen? He has to reply to one of the 2 emails I've sent since last Thursday....neither he or Don have made a peep.
I paid $600 for the front pair of spinner and backplate from a salvage yard in FL on ebay last year. but so far am having a tougher time. Given my desire to potentially upgrade soon, don't want to sink too much into it...just want to get it off the ground so I can fly to sun n fun and shop
