Need real advice on arrow spine and point weight
CB57:
Got out my scale, and weight varies 60+ grains, too. These are arrows I assembled from shafting. Also have beautiful professionally made 67-70# arrows, too. Yes, these were Strongly recommended for the 58# bow by the maker(!). Those will go up for sale while I look for some better suited arrows.
Don't have time to make my own right now.

I'm a little confused by your actual dilemma. Are you having flight problems with both bows that you mentioned? Or....? In general, the more center shot the bow the more forgiving your bow is on arrow spine variances. But there's a difference between arrow flight problems and arrows not shooting where you are looking. If the arrows fly true then that says alot. If they all fly true but all hit to the left or right....that's an entirely different problem.
If you want to sell your heavy spined arrows, PM me.

Tried sending this twice from phone. something not happening, so here, once again, is the rub.
Arrows bought for the 58# longbow were 67-70# spine. Seller (highly respected, reputable company) insisted I needed heavier spine than the AMO weight because I draw 29" and "125 gr points are heavy enough to require an extra 5+ pounds spine."
All the info I read suggests err on the side of heavier spine. They shoot consistently left at all distances.
Now, the previous arrows I had for the 58# bow (have a half dozen left) turn out to vary 10# in spine and 60 gr in weight! They were close to the suggested spine limits for my nearly center shot sinew backed, but now I don't know what I should do from here. The 58# bow is getting to be too much bow for me (shoulder issues), and want to shoot the lower weight bow, but need correct arrows. Have also started a hickory board bow that I would like to finish around 40#, but will again need to choose correct arrow spine.
Watching other archers shoot, and asking their setups, has left me even more suspicious of advice I've received. Frustrated.

I made a six test arrows, each 5# heavier that than the last. Bare shaft, so it's not that much work. Same weight tip on all six. Shoot them and see which is best.

I agree that the heavier spined arrows should work with the 58. The bow should just not be that finicky about arrows being slightly high. I shoot two bows through the summer, getting ready for hunting season. One is a Hill style glass and boo, maybe an inch wide, too-heavy-for-me, that I use to build up strength. And an osage flatbow that I shoot off the hand and is 10 lbs. lighter. I shoot the same wood arrows from both and they both go where I'm aiming. The heavier bow usually flings the arrows a foot or two higher than the other at 35 yds.
But I have switched from recurves to flatbows and have had to adjust my windage a good foot or two between the two, one being more center shot than the other. As the arrows become more mis-spined for the bow they will be harder to make them fly true without a perfect release. And yes they will group left or right but usually not without some flight problems along the way.
So if your arrows fly well but group to the side then you just have to change your aiming. Of course get some lower spined arrows, even a couple, and see what happens with the point of impact just to make sure.
