Just got done looking at the threshold in my catalog and so what if it has a cast riser and it is a bit longer. I guarantee this bow is qoing to be a shooter. I have a darton viper that is heavy as can be and is way longer, slower, I bet louder, and don't forget older, (Ive had it since 94 or so, I think?) with a cast riser and I shot it last week and the thing just pounds the arrows down range. And last year I took it out and smoked a doe at 30 yards. Enjoy your new Martin and Welcome to the Forum. Get a good rest, peep sight and the right arrows and most importantly have fun shootin it in.
