RE: conviece me which brand to buy
I'm not very brand loyal either. There several bows I would not mind owning. They all have a bow I like. Just shoot a bunch and pick the one that feels the best in your hand and meets your budget. I have looked at Martin, Jennings, buckmaster, PSE, AR, Parker, Darton, Hoyt, Mathews, Alpine, Proline and I'm sure a few others I am forgetting. I own a darton, a bowtech, a Martin and my girlfriend has an Alpine. I wouldn't hesitate to own a Mathews, Hoyt, Parker or AR. I personally love the grips on the hoyts and bowtechs, however I have small hands.
I wouldn't mind owning a merlin either, I have seen one up close and looked at them on the net a lot. To me they are more like works of art then archery gear. A quality product without a doubt.
You really need to shoot them and see what you think for yourself. Honestly you could walk in spin around with your eyes closed and just grab one and do well for yourself though. As long is it fit you.
