Genesis bow tuning. Finger savers. Dolphining. I need help.

I'm helping coach the archery team at my kids school. Several kids on the archery team have arrows that dolphin pretty badly and I'm hoping to learn enough to correct that. I'm the most "nuts and bolts" guy in the group of parents so it has fallen to me to try and learn what I can about tuning genesis bows and Easton arrows as used for NASP competition.

I measured the nock points at 3/8-1/2" above center for everybody.

So, as I understand it, best case scenario with max draw length, max draw weight, and crisp release the arrows are too stiff. At worst with a lower draw weight, shorter draw length, and mushy release things only get worse.

I assume this is going to be a case of minimizing rather than eliminating all arrow tuning problems.

Several kids have finger savers on their strings. The bows with finger savers tend dolphin the most. I'm not certain that the finger savers are causing the dolphining but noticed the correlation and thought I should mention it.

What can I do to try and eliminate the dolphining? I tried moving the nock point down to about 1/4" above center on one of the finger saver bows and it seemed to make things worse. How far above center is too far?

Thanks

Shibuya vs Axcel vs other top end sights?

So my budget has increased and i decided i'm going for a top-level sight for the target style recurve i'm building. It seems that Shibuya and Axcel are the top end, so for anyone who has experience with either one of them, or preferably both, could you tell me the differences, pros and cons, and which one is the best value? i'm planning on buying the most expensive, so the Axcel Achieve XP - Recurve or the Shibuya Ultima RC PRO Carbon Sight . If there's any other top end sights you think are better, let me know. I want this to be the first and last sight that i ever buy, and price doesn't really matter. Another question, on the Shibuya there's an option for "Single mount" and "Double mount." What do those mean? And lastly, is the sight aperture on either of the sights suitable, or is there better after-market apertures that are better? I'm sort of thinking that is something I should be buying from my local shop so i can actually te...

Is there any reason mediterranean and slavic draw shoot from opposite sides of the bow

When the release imparts the same twist on the string? It was my understanding that mediterranean draw has the arrow on the side opposite of the bow of the draw hand because of the twist imparted on the string affecting the arrow on release but that should mean that slavic draw would suffer from that problem. Am I missing something with this? Shouldn't that mean you could use a mediterranean draw on the same side of the bow as the draw hand and not have issues?

Are my new arrows overspined?

Are 400 spine, 27" arrows overspined for 30 pound draw weight? The guy just picked the arrows, cut them and gave them to me. my old arrows were 500 spine, 32" so when I said that they looked overspined, he just shrugged and said "the chart says they're ok". Can anyone confirm my doubts? submitted by /u/Astaziel [link] [comments] from newest submissions : Archery https://ift.tt/3pmjVLf via
