I am in the process of buying an aftermarket string and cable for my '05 Outback. I just went to a site to price Winner's Choice and the set was $87.00 - not sure if it's the same string and cable you are talking about, this is the description listed below:
409-40, Winners Choice Mathews Ouckback String 90 3/8 & Cable 33 3/4.
I mentioned this price to the guy at my bow shop and he said he thought he could get the set and install it for right around $90.00.
Have'nt priced the Vapor Trail yet but have been to the website. Heard nothing but good things about both of them which makes the decision even more difficult.
