I recently heard that Winners Choice was purchased by Elite, so I'm not sure how this will effect the company from a mass producing standpoint. Or if Elite has sole rights to the company? JJohnson can probably clarify.
There are a thousand different guys building "custom strings" anymore and with 99% of them using the same products or machines it's hard to differentiate between alot of them.
I actually left the factory string on my Element this year and after thousands of arrows it never twisted or frayed. If I go custom this time, I'll probably just have a local string builder build one for me. There are so many good ones now, it's really a personal decision.
Keep your bow tuned and your string waxed and I think you'll be fine with most of them :way:
