RE: 2 stroke Vs. 4 stroke
I saw a few two stroke .60's in last weekends Hotlanta SPA contest. Makes that I recall were, OS FX, Webra Speed, and Thunder Tiger. I am sure there were others. More two strokes than the last time I observed an SPA contest. I did not fly but really enjoyed shooting the breeze with several folks. King Altair was there. He had a new King Altair with a Saito 1.25, which (I think) is legal in novice.
