Btw, I ordered 2 8/6 MAS 3 bladers, 1 7/4 and 1 10/5. My idea is to try the 8/6 on my 25's. I am not sure about trying the 7/4 on a 25. The 10/5, I may try on my LA 40, and some plane with my Brodak 40. The B-40 is on a twisted wing Magician and I don't think I will try it again. I don't know if the 10/5 would be too small for an LA 46. I just ordered them today. Looks like an almost two week wait.
