Done deal... Picked up a Switchback. I also saw a couple more switchbacks and alpha max's for good deals!
I think you made a great decision. IMO the Switchback was the best bow Mathews ever built until the recent Chill came out. I've never had much issue with the Switchbacks nock travel. Maybe on some of the previous Mathews, but not the Switchback. Should be a very nice bow for you
One of the key things to consider with all Mathews single cam bows is the string. There is something about the Mathews idler wheel that plays heck with string rotation. You won't regret getting a premium string made with .014" or smaller serving material around the idler. Winners Choice, First String, America's Best,
(Newer) Zebra, Wallace, Vapor Trail any one of those or similar should be good. Key seems to be having plenty of clearance in that string groove.
