My dad got a Trykon about a month agoso I boughthis "old" bow from him. The "old" bowis a Vipertec with the spiral cams. The Vipertec has been the most accurate bow I have ever laid my hands on, but the Trykon is a very close second. For those who think the Trykon is a harsh cam, you should try the spiral cams! After shooting the spiral for a month, the Zephr cam feels like butter. The Vipertec feels a lot better in the hand-even dad agrees-but there is less shot vibration with the Trykon. To me, it is a toss up. Like has been said, it is best to shoot them and let the bow pick you. When you shoot it, you will know one way or the other. Just for info, my brother has a Switchback and while it is nice, it just don't fit me.
