Wait until the weather gets warmer. That is when you seperate the good strings from the bad. The heat will cause a less stable string to creep.

I am a die hard Hoyt fan, and absoloutely love the Tec design bows, I own 4 of them currently, however every single one has been unable to maintain peep alignment with the factory string.
While yours has not moved yet, I assure you that it will eventually move. For me, I found that out the hard way, sitting in a stand hog hunting in the Texas heat. I drew back and my peep had rotated 90 degrees. I couldn't see and didn't take the shot. The peep had been in perfect alignment until that afternoon.

I will admit the Fuse strings are better than the original Hoyt strins, they are no where near the quality where I would feel comfortable shooting a peep without an aligner.
