I made up some Trad Lites for my 52-57# recurves. I cut them 28.5" long for my 27" draw. I installed nock adapters, 9/32 glue on nocks. 100 grain brass inserts, 35 gr Magnus BHA and with my 125 gr Eskimo, it gives me 255 grains up front.
Total arrow weight is 600 grains. 5" Parabolic feathers, full helical, crown dipped and these arrows fly beautiful out to 40 yds. General rule of thumb with carbon...leave them longer. I don't like 3" of arrow hanging off my shelf.
I know a few people who shoot the Trad Heavies at the same weight as I do. They spine out 55/75, Lites 35/55. For me, they will make a tough stump shooting and small game arrow.
