Just to make sure you' re clear, Timberline does make fiber optic sights in addition to the No-Peep, which is not a sight but an anchor point reference tool.
You do not look through the no-peep, once set up for your comfortable anchor point, you look at it in your peripheral vision to make sure you are repeating your anchor point, then you aim with your sight pin.
I' ve heard good things about Timberline' s sights, and I can testify to the excellence of the no-peep. After using one for 2 seasons, I' ll never have a hunting bow without one, assuming something better doesn' t come along down the line...
I have no experience with your bow, sorry, but generally you read/hear nothing but good things about Parker bows...
