So after Paul's advice I went back down to the hanger with my tape measure and measured the blades. They ended up being 36 inches long, and the old Ivoprop that I had from last year was only 35. Also the new prop has some small cracks in two of the blades that just did not sit well with me, so I swapped out the new prop for the old Ivo prop. Pulled 5500 out of the field!!! Did not get a chance to really play with it as it started pouring on me as I lifted off so I just stayed in the pattern and put her back down. Definitely spins a lot easier with the Ivo so I am sure I will have to adjust my flying style a little bit.

I'm going to call Ivo again tomorrow and see if there is anything to the cracks- also recheck the balance on these blades because my old one is night and day smoother than the new one. Just want to say I really love this board- the knowledge and experience here is excellent. I don't post very much but I read all the time so thanks again guys( and especially Paul!!!)
