Ausie-guy,
Thanks for the Info! I have the OL4100 on order and use the no-peep. I miss the no-peep. For the time being we put a cheap sight and string peep on. The OL4100 came in last week but we needed to order a left hand model, so I'm still waiting. I ordered it with the green pin because I have found the green to be the best pin also.
