I just bought a Hoyt Ultra Tech and love it. Expensive and cutting edge technology. Parallel limbs do not give you automatic hyper speeds but they do give you a no hand shock bow. There are a bizillion bows out there. Try them all and buy the bow that feels the best. I did and do not regret my purchase. One of the fastest bows the Hoyt Turbo Tech @ 330 ftp, smoking hot I would say. I did not buy a parallel limbed bow because I didn't like the feel of the draw force curve but lots of guys do. I also do not like the appearance but lots of guys do. Again pick them up and shoot them. Most feel pretty different. The right bow for you hopefully will feel like a good idea, mine did! You'll know which one it is when you hold it and or shoot it.
Good luck in your quest. You'll enjoy your the search.
