If you don't have a set of Quality strings on your bow, then get some! They are one of the best investments you can make.
The only peeps I will use or recommend are:
1. G5 Meta Peep (blue)
2. Fletcher Tru-Peep (black)
3. Redeye Peep (red) This is a peep I have just started stocking and although my experience is limited they Look Sweet!
