The problem with any of the pro-series models, including the LD, is that the bolt for the centershot adjustment is blocked by the Tec-riser on hoyt bows. And since you are planning to put it on a Katera, IMO it is better to go with the hunter model, it works just as good while being easier to adjust centershot. I use and love the QAD ultra-rest, you wont go wrong with it.
