What weight arrow should I use for a 40#' s @ 28inches recurve? What spine? The arrows I am currenty shooting tend to kick up high during flight. Thanks.

If they are kicking up, then your knock height is wrong, probably to low for your style of shooting. If you are shooting wood arrows then try a shaft spined for 50 to 55 pound bow. for aluminum use the Easton charts.

I agree with Richard about the nock height.

What spine arrows you need depends on what kind of bow (recurve, reflex/deflex longbow, straight limb longbow, selfbow) you' re shooting, how centershot it is, what your draw length is, how clean your release is... About the only way to determine what is right for you is to figure out approximately what spine you need, then try shafts that run two spines under and two spines over that. Pick the one that shoots best.

Arrow weight comes pretty much under personal preference for what you' re going to be using the bow for. Target shooters like lighter arrows, hunters go heavier.

What arrows are you shootin now? Like Rich said, if the tail kickin high is all the problem you' re having just move your nock point down. If the spine was wrong they' d be kicking left or right. If a change is needed, I' d reckon trying something around 45-50# and 50-55# for wood arrows (I don' t know much about aluminum or carbon sizes). See which is closer to the mark and go from there. Othere variables depend on if you' re actually drawing 28" , how long your arrows are, and point weight. But if kickin tail high is the only problem I reckon you can work with your setup and fix the problem without change spine weight.

Thanks guys, I think my problem is that I just realized my string is about 4 inches short, Im going to get a new string and see how things work.

For an Easton Legacy shaft:
Recurve
125 gr. tip
40#
29" arrow
They recommend:

Shaft Size ------- Shaft Grains/Inch
2016 ------------------- 10.56
2018 ------------------- 12.28

In my experience going a little underspined is better than going a little overspined. This is less obvious with a bow that' s more center shot than one that has significant paradox, but it' ll rarely hurt to do it as long as you don' t overdo it. Probably no more than 10 pounds underspined would be okay, especially if arrows precisely matched to the bow' s draw weight don' t seem to work especially well.

Center-shot bows are more forgiving over a wider range of spines than bows with significant paradox, that is the arrow is positioned off center. That' s why one can sometimes get over spined arrows to work in a center-shot bow. But underspined arrows will work in practically any bow as long as one doesn' t overdo it previously noted.

This all presumes that the bow is correctly tillered for the rested arrow position on the riser. If it isn' t, no spine will fly right. It also presumes, as previously noted, that the knocking point locator on the string is correctly positioned. Finally, it' s possible that one' s release style might make all of these assertions more or less moot.
