Retitle your thread, "String Creep"... Remember "stretch" is a temporary elongation and "creep" is a permanate elongation....

People refer to string stretch when in reality it's creep....


Anyway, I use the Super Peep on my bow which allows you to screw in apertures of different sizes including lens...a little heavier but I use a scope lens from time to time.

If I would not use this, I recommend a Tru-peep...they now have some larger sizes to match up with todays rounded sights....
