Getting set up with the right draw length and release combination is important. Weight is not. A real bow tech/archer is key, and as Emperor eluded to dropping a pile of cash starting out is not. There is a $300-500 market full of adjustable bows some are better than others I have a Bear Cruzer II, my wife has a Diamond Intrigue. They were roughly the same price but I think hers shoots better. I’m still on the cheap end of my evolution as an archer. I bought a fully adjustable style bow, the first year I had a tech set it up and I was comfortable and happy, but my anchor point wasn’t consistent and I couldn’t put my finger on way (still a young archer). I went to buy a second set of arrows and a different bow tech at a different store, pressed me on length. And I told him we set last years arrows at standard length, but when we looked at my draw he noticed I could drop an inch in DL and almost 2 arrow shaft. Long story short my groups tightened up. I’ve still got a long ways to go to feel good shooting past 30 yards but I’m getting there.
My two cents is buy a cheaper bow that is a RTH (ready to hunt) package try some releases (stick with one that buckles no Velcro), and find a tech or archer that will work with gear that’s not top tier gear. Once you are to the point the cheaper adjustable rig is holding you back upgrade.
Some really good advice here. I know it's far from the OP, but Gotham Archery in Central/Baton Rouge is worth the drive. They have an amazing, helpful staff, a huge indoor 3-D range, great selection of bows, arrows, etc. They offer lessons, and absolutely will not take advantage of you. I went to a couple of other stores first and was not impressed with customer service - everyone was "too busy" during hunting season to help out. I ended up buying a PSE Stinger online, RTH, because of the price. It's not a bad bow for my purposes, but I wish I had just started off at Gotham and let them walk me through the whole process. Can't recommend them enough.
