I have that video icon right on my desktop and have watched it about 100 times,lol. It does seems to fly pretty darn well with the 100. Minn mentioning that a bigger engine might make up for some of the weight he had to add to the front for balancing,plus the added power might be ok is what was really making my decision harder.
Now if I do decide to go 2 stroke,I have to try to figure out what size 2 stroke would compare to those 4 strokes. I'm usually a very decisive person too....thats the bad part!
