I have a quick question for the serious Hoyt shooters out there. I just signed a deal with a shop to shoot Hoyt for them. I am in the process of picking out my bow right now. I figured I was going to shoot the Katera XL, but as I am looking I am not sure now. The Katera XL has good ATA at 36" and a nice BH at 7.5. However, I see the Katera XL has xt 500 limbs, where at the 737 has xt 1000 limbs, the pro elite and ultra elite have the xt 2000 limbs. All of these bows are pretty close in ATA, with the pro elite having the biggest BH at 8". What I don't know right now, is what the difference in the limbs is. The Katera XL has the fastest IBO speed, but ASA limits me to 280fps, so speed is not a huge factor. Can anyone help me out by explaining the difference? I figured on calling Hoyt to have them explain it, but that will have to wait until I am out of work, so I thought I would throw this out there and see if anyone can help me out here. Thanks in advance.
