RE: String Peep or Timberline No Peep
An experienced shooter going to the no peep sight is going to have some problems as he is going to have to relearn everything he's been taught. A new shooter is a different story, you will be learning to use the no peep without the distraction of what you used to do with a peep.
I use the no peep and love it. It can be more accurate for a new shooter because you will see the effect of hand torque while peep sight shooter won't. Another advantage is you won't feel compelled to squint as you would in a peep sight setup. But by far it's biggest advantage is the extra shooting time you get during the early dawn and late dusk. That's when deer are most active. I've seen peep sight hunters give up while I still have another half hour of shooting light left.
It's a great idea and I encourage you to get one. I set my own up so it can't be all that hard.
