I've got 2 Burris XTR II's, a 3-15 and a 5-25. I know a lot of people don't care for the XTR II's but that's what I started with. I've been thinking about getting something else, apparently I'm doing too much sitting doing nothing. I don't need another scope but what the heck. I've been considering either an Athlon ETR or a Chronos. Seems a lot of people think there's not a lot of difference between the two and since the ETR is slightly cheaper was considering it. Will the ETR be a step up from the XTR or should I go up further to Vortex Razor?
