I bought an 04 Patriot single cam with TS-1 material and that is the only complaint I have on my bow.

the summer of 04 i shot it in the extreme heat 95 degrees+ and the string streatched a bunch. I was at my dealer once a week twisting srings and cables.

It finally quit streacthing but I still can't get the peep to rotate exactly how I like it, so this year I am either getting my bow crackerized or getting a set of vapor trail string and cables for it.

I was told when I bought the bow that bow tech was contracting out the strings and cables ( maybe jared or pat can confirm that) in 04. I did talk with one of the Diamoond Reps last year and was ensured that BT and Diamond were making the new strings inhouse now.

But as long as you keep an eye on your timing marks you will be good to go.
