I have a quick question.... Does a brand new bow require a certain "break in" period? You know, like how a new car has a certain break in mileage period?

My brand new Reflex Highlander is all setup and shoots great. Very fast, smooth, quiet, and almost zero hand shock.

(See the photo below...)

67# draw weight, 29" draw length, 75% letoff
Beman ICS Hunter 340 arrow is resting on a Quiktune 1000 lefty rest.
{Disregard the crappy old Tru-Glo lefty sights in the photo. I threw them on just so I could shoot the bow and get it tuned up, broken in, practice, etc...}

Anyway, I have just started noticing a very very slight cock vane contact/rub mark on the Quiktune 1000 rest. It is probably 1/16" or less. It doesn't seem to affect arrow flight (that I can see), but is a minor annoyance.

Second question: I read about checking the tiller and looked at mine with a ruler. From what I can determine, the top tiller is 8 1/4" but the bottom tiller is 8 1/8". Shouldn't the tiller have to matchequally?

I have probably put two dozen shots through the new bow already, if that matters any...
