I need some help. I'm going to order a new Hoyt ultra-tec when the 04's become available and need to decide on which limbs to order. What kind of speed can I expect from an Ultra-tec w/ XT3000 limbs, 28 1/2" draw, 60# using the 75% let-off cam & 1/2? Other than a few local indoor leagues this winter, I will be using this bow for 3-D next year, which all the shoots I attend have the 280 fps speed limit. I'd rather have the longer axle to axle of the 3000's but dont want to come up short on obtaining my speed of 280 (+/-). I realize Hoyt may come out with something new, but if they don't, I want to have my stuff together, and ready to place my order. Thanks in advance for your input.
