Posting comments here rather than highjack the "fury vs rhino" thread.
Glad Brownell's policy has changed on giving some info. on their materials--wish they would be a bit more forthcoming as to where they actually get their materials; i.e. BCY is proud to use DSM as their supplier. As a general rule DSM also requires manufacturers to note their products are made from DSM material.
Apples to apples, Fury is in the same family as BCY's 8190 (100% HMPE, UHMWPE, etc.--there are several generic names for it)
SK90 is a unit of measurement (look up denier)--has nothing to do with the brand of HMPE used. BCY uses nothing but DSM's HMPE, Dyneema (Dyneema is the trade name).
There's no way any 100% HMPE material is going to be as stable in higher temps as BCY-X. It's just the nature of HMPE--it's a plastic fiber. That is the whole point in integrating some Vectran into the material.
The primary reasoning behind the smaller diameter strands is flexibility, which equates to a tiny speed increase with wheel bows. Won't affect stretch or creep. That is affected by the material itself...450+ is relatively "fat", but has virtually no stretch or creep due to the Vectran in it.
BCY's 8190 is smaller than BCY-X. It's made from the highest grade (SK 90) Dyneema available from one of the most respected fiber manufacturers in the world (DSM). It doesn't stretch/creep much, but in higher temps it's not going to be as stable as BCY-X; i.e., it's going to have a little creep. How much depends on lots of variables like draw weight, actual temp, strand count, etc.
As far as I know, Brownell has no material comparable to BCY-X. The next best thing would be BCY's 452X, which has been the standard in the wheel world for years and years.
I know...we don't shoot wheels. However, when it comes to strings, we are looking for the same thing. Consistency, durability, stability, a quiet shot. That side of the sport has the money and equipment to do real tests; and on the high-end it's way too competitive to not take advantage of anything that can give an edge.
But, like I say on my site, don't take my word for it. Everyone has their preferences--do your own tests and see what works best for you.
BCY has been encouraging this for the last few years by setting up at traditional venues and making deals and giving samples. Since that began, and more people have been encouraged to do their own "tests", sales to traditional shops has gone up exponentially.
If you make strings and/or have a shop and want to do your own comparison, just give me a holler. I can help you get a sample of BCY material to try out and then you can make your own call.
