you would be well ahead with a Titan from Tradtech. i'm not even sure if the limb interface on the buffalo is the same as the new hoyt OLY limbs so you may only be limited to those limbs on the buffalo.
with the Titan, you can use any brand of ILF limbs, custom bowyers are starting to offer them, and Tradtech also makes a set of longbow limbs instead of just recurve limbs. WAY WAY more options with a riser that accepts ILF (International Limb Fit) limbs. you can pay less for a complete set-up than the buffalo or the sky is the limit depending on what quality limb you want. jmo
