RE: rest on recurve??
The shooter in the video is Terry Ragsdale. I can't think of many people in the whole worldthat have a cleaner fingers release. Remember that a fingers release also adds a lateral component to the string's thrust. The string is pushed sideways out of it's perfect plane of travel when it comes off the fingertips. The lateral thrust increases the amount of flex in the arrow, and it's why the centershot adjustment is slightly outside true centershot. If you're really interested, they do have a video of an intentionally bad release. Go to the main video page on the Beiter siteand check it out.
The video is researchfootage from Beiter, and that should speak for itself. They use their slow-mo video to help them design and manufacture some of the world's finest archery accessories. They would not be using severely underspined arrows for their r&d footage.
The arrow in the video is not usingthe bow's power efficiently, certainly, but that's just what happens with a fingers release. Why do you think release shot arrows are 10-20 fps faster from the same bow than the same arrowsshot with fingers? The answer is right there in the footage.
Fingers shooters can't do like release shooters. Over the past 10 years or so, release shooters have been doing everything in their power to eliminate paradox by using very, very stiff arrows.
Fingers shooters have to select arrows that are spined just right, so when the arrow stabilizes from paradox they will be flying straight on the line of sight. If they are too stiff or too weak, the arrows will fly well off to the sides. The more centershot the bow, the stiffer you can go with arrow selection. The less centershot the bow is, the weaker you have to go in arrow spine.
Another point... Paradox with a compound is less than it would be with a recurve or longbow. For one thing, the arrow pass on the bow's riser is cut well past center, allowing for a lot of lateral adjustment. Most recurves do not have the same degree of centershot.
Also, the arrow is in motion before the cams roll back over and hit peak draw weight. (With a recurve, the arrow gets the full force of the bow immediately on release.) Maybe the compounders who use the wb for shooting fingers are using overly stiff arrows too, which would also reduce paradox. Maybe, just maybe, they can reduce paradox enough to successfully use a wb. I'll reserve judgement until I actually see someone do it (I never have seen it done) and until I witness first hand how well they actually shoot, how consistently accurate they are, and how many fliers they get in their groups.
