Wow i am glad to know that before i spent my money on the 26/10 i get 6100 on the menz 27/10 and 5900 on the nx 28/10. I havent checked the rpms yet but i ran the msc today and could notice just a slight rpm drop but could really feel the pull and motor sounded more healthy. I didnt tach it but i am just waiting to see how it flys with the msc on it. Thanks by the way the Brison will get stronger as the motor breaks in . Took about 10 gallons on mine before it really felt good and running to its potential.
