    Default Barnsdale deflection numbers.

    Okay long story short, I just picked up a 2011 onza 3 and want to put barnsdale limbs on it. If I were to want 60-65lb max limbs what deflection would I need.

    How can I tell? Draw length as it sits feels a half inch long for me so 28.5 And its in the number 4 spot on the mod. So my guess would be the 2.0s

    Sent Dave an email last night. Hope to hear back soon the onza 3 was by far and still is by far my favorite bow I have ever owned. 80 yards never felt so close once I saw the deal on this one I had to pick it up and I will move one of my mathews.

    My Nemisis (similar to the Onza) has 1.5 cams and 195 Barnsedale limbs for 50#. That would be just about 40# with 2.0 cams. Stiffer limbs have a smaller deflections number. I haven't dealt with anything with the 2.0 cams so don't take this to the bank, but I'm guessing you'd need 155 limbs for 60# or 135 for 70#. Much as I'd like to be sure, I'm not. It's your money so I'd wait for an answer from Dave. Heck you could even call the guy. He's fun to talk to---just like an ordinary Joe.
