I would use the heaviest aluminum or carbon shafts suitable along with Magnus 125gr 2 blade heads.Easton' 2018 should work well as far as aluminum goes.Check their charts for carbons.I used 2018 along with Tru Taper adapters/Magnus heads with my longbow before switching to carbons.The carbons I'm using now are no longer available.I'm not sure offhand what size would be equivalent.Good luck!
