The Vectrix and the Drenaline were both the same in noise to me; both super quiet. I personally think the Switchback is a better bow than the Drenaline. Mathews jacked the price of the bow up $100 this year over last years price and I am not kidding about the very noticeable handshock. That coupled with the fact that you are going to need to replace the Mathews string, from what I have heard and read ,if you want to get away from a rubberband on your peep. The Hoyts Fuse string is no creep and pre-stretched and will shoot excellent without a rubberband to align the peep. My Trykon's Fuse stringworked excellent as well and once setup at the shop I never adjusted it after hundreds of arrows shot through it. This years' new Fuse string is suppossed to be even more advanced.
