I have a set of Tommy Armour 845s Silver Scot irons.  What would be a good shaft to set these up for my 14 year old grandson?

Silver Scots were nice in their day. Might be more cost effective to get him a new set of M890s or ST Irons.
As far as flex, that’s up in the air. My son at 12 years played stiff steel DG. Neighbor kid played A flex graphite. They were fit at Golfsmith in the Chicago area in 2000.
