B50 to D97

[Squint]

Looking for a little advice,Ive been shooting B50 forever,I shoot 45 to 47lb recurves with 12 strand B50.Ive ordered some D97,how many strands of D97 would be about equal in thickness? so I could use the same size serving Ive always used.Im not looking for a skinny string,would I have to pad the loops?Bows are FF compatable.  Thank you  John

Im not sure about the size comparison, but my 45# super grizzly came with a 16 strand D97 string if that helps.

With all the other good choices I have no idea why you would put any effort into making strings with D97...read some of the posts from Chad Weaver aka LBR

Around 14 strands should be close to 12 strands of B-50.  I'd still pad the loops out to 18 strands--use the B-50 for that.  It may not be required, but it will make the string quieter.

What type nock do you use on your arrows?  You can get a good fit with the right size serving.

Dynaflight '97 will be a huge improvement over B-50.  I used Dynaflight for around 15 years and loved it, but now I'm partial to BCY-X.

If I can help, just holler.

Isn't that what Black Widow supplies with their bows?  

I guess crappy strings for crappy bows, huh?

BTW, a couple years ago I put one of those D-97 strings on my 55 year old Bear bow and was amazed at the improvement in about all respects.

You're gonna love the switch to D97 vs B50.  I hate B50 with a passion LOL.  I call it "shock" cord LOL.  

Nothing wrong with D97, however I am partial to the newer materials like Rhino and X for their durability and appearance as well as the fact that once prestretched prior to build they do not budge one bit when you set your brace.  (I just tried an X string that came on a bow I acquired in a partial trade not to long ago, great stuff and to me very similar in appearance and durability to Rhino)

While I wouldn't call it crap, I will say that every other high performance material that I've tried has performed better for me than D97.  Only slightly better on some bows, but very noticeable on others. Therefore, I rarely use D97 anymore since switching to the higher grades of Dyneema and the Vectran blends.

Squint, it seems that you're going to lose a lot of the advantage of the FF strings if you build it up to a fat string.  A ten strand FF would do well, just pad the loops to 16 strand and build up the string under your serving with teflon tape so that it fits your nocks once served......you'll be good to go.

Thank you LBR,Im using X nocks and H nocks  

Depending on how you like your nock to fit, and what size serving you are using, you could probably do fine with 12 strands.  I'd still pad the loops to 18 or so though.  It's quick and easy to do, no down-side to it.


Dynaflight '97 isn't crap at all, and the difference in the newer materials isn't huge in most cases.  You'll see a bigger gap in the difference in stretch and creep when pushing the limits with low strand counts.

Just like original "Fast Flight", when Dynaflight '97 hit the market it was the best there was.  Since then, better base materials have become available, primarily higher grade Dyneema, which allows for a "better" (less stretch, less creep, better durability) string material to be made.  There's still not a big difference in Dynaflight and the highest grade 100% Dyneema material made (8190).  BCY-X is a blended material (83% SK90 Dyneema, 17% Vectran).

Personally I shot my highest scores and won more tournaments using a Dynaflight '97 string than I have with anything else...but I used it for around 15 years.  I wouldn't have a problem going back to it.  BCY-X just makes a little better string for me.

Thanks everyone for all of your help,,especially LBR,your the best!  Thanks again   John

For me D97 is just fine; but if you leave some bows strung it will creep, so then you might want to check out some other materials that Chad mentioned in this thread.

For your draw weight a 14 strand D97 will be great.  I shoot only ASL's and don't pad the loops, but Chad's advice to pad to 18 may be worth doing depending on your bow.  I'm really happy with the performance of D97 and it's cost is certainly more wallet friendly than some of the newer materials.  I have tried some of the newer materials and always go back to D97.

Lots of people are more than willing to shoot bows at less than their most efficient...I too was willing to do that until I tried something better...I guess if D97 was the best material that that Brownells and BCY could come up with they would have stopped their research and development in 1997 eh

To each his own, brother!

Exactly.  Some like selfbows, some like Hill bows, some like the latest, greatest ILF contraptions.  It's all good.
