I am sure there is some fast bows out there But, my Martins have always been pretty fast and pretty Smooth...However, I normally shoot around 60 pounds ,,I try and tune em up to where they feel good to me and if that is 57lbs or 63lbs thats ok with me ...I am getting 280 out of my Aillen X with a 26 inch draw at 60 lbs with just adding in my head about a 350 gr arrow ...I think ,that is about as fast of a bow as I can get ..What other bows in the Martin family do you think would be faster...Thanks
