Nothing wrong with using what you like, but just to clear up a few things.......
1.) I've seen no proof that FF type materials are "hard" on a bow,, at least a bow that's built to use them. Of the bow failures I've seen, most (by a big margin) had only used a dacron string. The only failures I've seen that could be directly attributed to a FF string were on old bows (not made to use FF materials) with unpadded loops and a low strand count--I've seen this twice. I've never had a dacron string on my #1 bow, and it's served me well for around 10 years and shows no signs of giving up any time soon. I'm pulling
[email protected]" on it.
2.) FF type materials aren't inherently loud. I get regular comments on how quiet my bows are (the two I compete with). Each has one set of "cat whisker" silencers. Proper tuning and silencer placement goes a long way. Padded loops can also make a huge difference in string noise.
3.) Not all of these strings are "piano wire" strings. I never did care for those either (and that's what I've called them for years), until about a year and a half ago when I started competing with a selfbow. I still use a moderate size string on my longbow, but the small string on my selfbow really helped the speed. The handshock, which was just about intolerable for my elbow with dacron, was greatly reduced as well.
4.) You don't have to pad out the serving area to get a proper nock fit, unless you go with a low strand count (piano wire) string. I shoot Bohnning Classic and Mercury nocks, and they fit my longbow string just fine.
5.) There's a lot more to gain from these string materials than speed. Reduced hand shock, reduced stretch, reduced creep--all of which mean better consistency--and increased durability.
6.) There are lots of different "FF" type materials--some bows seem to "like" one over the other. My personal favorite is Dynaflight '97.
7.) You are crazy!
Again, if you like dacron, go for it. Just wanted to clear up some common misconceptions.
