Congrats on a sweet win!!! Im guessing it was in a raffle?
Best thing to do is get to a GOOD pro shop, not just the closest one but a GOOD one and have the bow professionaly setup for you. Second take all equipment suggestions with a grain of salt, everyone is guilty of being biased in one way or another and hey thats fine, but whats best for me or joe or larry or moe may be horrible for you and dependent on what your desires and needs are you may not need to drop near the coin others do or will suggest. Third try everything and see everything for yourself before you purchase, that way like I said above its best for you!!!! Fourth and most important have fun and practice!!!!
I haven't shot a Z7 yet but based on what I have seen, read, heard, it is one of the best hunting bows Mathews has put out. Many positive reviews on that bow. Congrats on the winfall and enjoy it. The other good thing with that bow is there is a pretty high demand for them right now so if it doesn't work out for you you can sell or trade it for something else and come out pretty good on the deal.
