Greg, I put an Imco extreme SC lower on my 25 Eagle at the same time I added the PC, I'm not sure if it helped me at low 80's but I will tell you that it handled better.

My experience with Hydromotive is they know what they are talking about. When I called about props and told them my setup, they told me exactly what I could expect and why. They hit it EXACTLY. I would very much trust what they had to say.

There has got to be some nose cone guys out here? Probably added nose cones before they went fast? g
