The one thing I disliked about the biscuit was that it would tear up my fletchings.
Ease of use, security of mind, and accurate enough that at the grassroots level my Bro is placing 2nd through 5th at local 3D events around the State. I placed 4th through 8th, but that is more my lack of ranging experience than the WB.
For highest level competition, a person probably wants something different. But for the cost in terms of hunting/hobbyist 3D/backyard shooting it can not be beat.
I've put hundreds, if not into the first thousand, of arrows through mine and it is showing hardly any wear at all. For those worried about the wear, a replacement disk every year for 5 years still only bring it up to the cost of a high end drop-away, with a lot less tuning issues.
Installing the WB is a breeze compared to most drop-aways for the average DIY'er. I find it hard to believe that for the average person that installing something that needs to tied down and timed with your draw is as easy to install as a fixed rest (prongs/WB).
You do need to tune your set-up to use the WB. Any set-up needs to be tuned. For drop aways it is the buss cable, for prong and WBs, it is the nock/vane alignment.
1. if there is dark markings on the vanes, then the shooter needs to rotate his nock a little more and clear the black bristles.
I've put hundreds of shots through my WB with little, if any, wrinkling. The waves I did get was from the vanes passing through/by the center. Once I figured out how my nock needs to be turned for my draw length, poundage, and arrow specifics... no more waves. No different than a prong rest or the NAP 360. People need to tweak their set-up for best performance.
2. to get rid of the waves there are two well known and noted solutions.
A. pass hot air over them with a blow dryer or candle. NOT close, just enough for them to warm up and straighten out.
B. put them in warm water. The warm water will also straighten the vanes without melting out the glue.
Just a bit of advice for those worried about using a WB and Wavy Vanes....
To keep the leading edge from catching and peeling back, put a dab of glue on the leading edge.
Lots and Lots and Lots of test show only like a 2-4fps slowdown with WB.
And Lastly,
There is no better endorsement than seeing people who make their living shooting a bow (all those hunting programs) shooting the WB as UNENDORSED equipment. On many of those shows you will not see Carolina Archery listed as a sponsor. The WB is the shooter chosen rest. When they need to make the shot that counts, so they can record the kill, put it on DVD, sell it, and put money in their bank, they use a WB.
Are WBs accurate? As accurate as you are out to 40 yrds definitely.
I made the move mostly for hunting reasons but have found that I seem to be shooting even better groups on targets. Yes, there are some marks and light waves in the fletches but this doesn't seem to be affecting flight noticeably. I had absolutely no tuning problems as I took measurements on the old rest before I removed it. I am going to switch to blazers in the near future as they seem to eliminate any of the concerns about the WB and fletch damage. Seems to me that you can't go wrong with the WB
