That is correct, a single blade is best of all.
In general one should expect a drop in cruise speed and an increased takeoff time and climb - and LOTS SMOOTHER.
All three blade props are not created equal. Viking found the Sensenich to be quite inferior to others, the Warp drive pulling the hardest. Ron gets off the ground far quicker with the Warp than the two blade people. If I recall correctly Vans only tried the Sensenich three blade, they will not share what figures they had with it, but that they would have to re write the POH. Most people seem to agree, the sacrifice in speed (if any) is far outweighed by the smoothness. Shaking everything apart is never a good thing in an aircraft.

I would have any aircraft dynamically balanced after installing the prop and painting the spinner. The two blade should be smooth also.

Two to go, three to show.

I think it would be much cheaper to carry around a spare blade and some velcro.
just pop the third blade on while parked.

If going for bling, carry TWO spare blades and make it four! Claim you are a Reno Racer..

I flew a Remos GX today which has a Rotax and a 3 bladed prop, it felt pretty smooth, I think I even noticed it when shutting down.
