Now as far as John's Customs strings....Over the years I've shot A LOT of strings from A LOT of builders...From small builders at local shops to the big guys like Winners Choice & Vapor Trail..I started shooting John's strings back in 2008 and have been with him ever since. IMHO he builds the best you can get, he's very precise on his lengths, he stretches everything so there's no creep and his serving is second to none...Serving quality and precise lengths are what seperates the good builders from the great builders. As far as the 8190 material goes, I've shot it on a few bows since the 8190 hit the market and I really like it...Very little stretch in it, a lot like 452x, but it fuzzs less than 452x...So with less fuzz you don't have to wax it as much, less wax equals less build up in/on the strings...Excessive wax adds weight to the string so you lose performance over time and wax holds dirt and that leads to strings that look nasty over time and can also lead to more wear on the strings with all the dirt that gets in them. I've shot most all of the string materials on the market, I've been happy with 8190 so far...John really likes it too, he gets less stretch out of it and better speeds.
Hope J-Daddy don't mind, but I'm quoting his reason for his string selection to this thread...
I know that I need new strings this year and may give these a shot as well! How are you supposed to measure your appropriate string length?
One other thing to add is that some "not many, but some" of the custom builders have their OWN lengths they use on string/cables...Just for example, if a bow calls for say a 58 1/4" string they might have found out that they pick up 10fps and a more correct draw length if they use say 58 1/8" on the string...Not many of them have this perfected but a few do "my builder does"...My builder does this on a number of bows and you always see performance gains from it.
Interesting.....I may have to give him a try. Do you have pricing and contact info for him?
Yep, I know Tom and he builds really good strings as well...Heck of a good dude too.
