Pick My Spine

[Valkyrie]

I have found that I get great flight with Surewood shafts spined at 65-70 and 60-65 with the edge going to the heavier spine.  I am able to predict the shot, feel a better release and observe better flight with both arrow weights.  Now I need to decide which I should go with.  Im leaning to the heavier spine.  The heavier spines are not as sensitive to a bad release or lapse in form

What say you?

You seem to have answered your own question.

I would go for the heavier arrow.

If the higher spine shoots well opt for it. Tuning is tuning and the point is superior flight. Pick the one that flies best.

My 60# Blacktail loves 80 lb spined Surewood shafts!  

If you're shooting a recurve you can usually go up in spine.

Have you shot them thru paper or tried an even heavier spine?

If I recall your earlier post, you where shooting 51#, SK, and drawing it 30 or 31 inches, but you did not mention the point weight. If it were me, because wood shafts are spine on 26" centers, add for:
3 inch, 5#/inch over 28", = 15 lbs
FF string,                   5 lbs
Center shot                  5 lbs
Point Wt., 5#/25gr over 125  5 lbs

Total                       30 lbs

That might suggest 75 - 85 lb spine especially if you are shooting 160 gr field points. Add more if you go with a heavier point or broadhead. Next put some medium wt. kraft paper on a box frame (wood or cardboard) to paper test. Elite Arrows tells you how on their website.

Hud,  I was able to do a paper test and they show a left tear about 1/2-1".  Im using 125 field points.  I thought of two options, either trim an inch from the arrow which will give me half an inch at the front of the arrow shelf and lower the brace height a little or go to the next spine up.  I want a heavier weight arrow so trimming it shorter isnt my first choice.  Probably go with 70-75 spine and call it good.  I am really excited that I am able to get arrows to actually fly naturally to my point of aim.

ETA:  I tried cutting an inch and with my long draw it just won't work.  It brings the point slightly on to the shelf and I don't want that small of a clearance.
