Wyvern String Question

[GaryDowdy]

I got my Wyvern string in the mail today and I'm very impressed with the quality. However, after installing it, it sets about 3/4" about the highest recommended brace height marker. I have very little twist in it. I let it sit cocked for an hour or two the carried it and and fired it. No strecth, still off the mark by 3/4". Anyone have any suggestions? I'd like to have it 1" lower, about a 1/4" below the top mark.

Thanks!

mine was the same way.. its setttled right at the first mark now after a week. We shot it even with it right before the first line and it did fine. Took basically all the twist out also

Cool! I got a RED/Black sting and it looks wicked on my ExoMag. Gator hunting tomorrow, so I'll change it back with my flemish and fiddle with it next week.

How do you like yours?

Seems to me that those strings are made a tad on the short side, with the thought that they'll stretch. My guess is that they are also being made to be used on an Excalibur with the angled riser. Therefore if you are using an older Excalibur (i.e. straight riser) the string will be even shorter, since the length from limb tip to limb on them is 1/4" longer.

I'm fairly certain Excalibur went to the dual string mark system on the rail at the same time they went to the swept riser or maybe not.

You're partial correct Bob, they were both introduced in 2004. However the swept/angled riser was only avaiable on the Exomax in 2004. It wasn't until 2005 that the angled riser was available on the Exocet and that the Phoenix was introduced.

My point regarding string length was that one would assume that all Excaliburs would need the same length, when in fact the ones with a straight riser need a slightly longer string.

I have an ExoMag.

I don't want this to sound like anything but a helpful comment. So please do not think it is anything but being helpful. Today's high performance string material has very low elasticity. That been said you need some twist to a string made with string material with low elasticity. Strings made from low stretch stuff like Astroflight/452X/Xcel etc should have quite a few twists. More twists mean more weight and a slower string but the difference is very very small. The twist acts like a shock absorber taking the edge off the shock that is produced when a shot is taken and sometimes in the event of a dry-fire. I would speak to David and explain your string situation and see what he thinks.

Thanks, Boo!

Make sure you are twisting both ends (kidding)

I have had my Wyvern String on my Equinox for about 3 weeks now. I did get a slight amount of stretch. Nothing to where you are going to get 3/4 or a inch below the longest brace. I have a few twist in it where it isn't a worry. I think it stretch all of a 1/4 inch on the rail "AT Most". I would say I have about 75 shots out of it and have had it in the cocked position for hunting for atleast 24hrs now.. Bottomline, Im extreamly pleased with this string vs the 2 others that I have had on my bow.

Hi All:

We basicly designed the string length to achieve two things. One was to work off the shelf with the STS without having to twist the crap out of it and two to set the height on the high side to get the most poundage from the bow (drawing it back to the highest amount that Excal recomends.) When we did our testing the length never came up as an issue as most everyone either had theirs on a high brace height or had an STS. We have decided to make a 1/4" longer string for those that want a lower height. If you have one of our strings and want to swap it out for the longer version let me know but we basicly did the string that way for a reason and so far it seems to be working well

Thanks
Wyvern

I didn't expect any less from you David, thank you!

[GaryDowdy]

Thanks, David! I was also wrong, my Exomag only has one brace height line... the other was a perfect reproduction in the layer of wax.(which I have cleaned off) If David designed the string this way, I am happy with it! The string is of excellent quality!

This is another reason I love this forum. I'm learning new things all the time I know this should have been common sense, but I never gave it another thought until he mentioned it! Makes perfect sense now...

Gary, from the pics I've seen, I don't doubt that the Wyvern string made with Brownell Astro Flight is of excellent quality.

I say that because, I'm also using Brownell Astro Flight to make my most recent strings. The performance I'm getting with my strings is very impressive. My shot consistency and accuracy is just amazing. I'd have to say it's the best material I've used to date.

Even though my strings are flemish twist, and more conducive to being twisted, I would have to imagine the your endless loop string should perform just as impressively, if it fits your bow like it should. That's the area I'm sort of wondering about.

Like I stated in my other posts above, any older Excalibur with a straight riser, is 1/4" wider limb-tip to limb-tip than the current angled riser Excaliburs. Since you have a straight riser Exomag, I honestly think that you would be better served using the 1/4" longer Wyvern string.
