Pat B:
Just remember if you buy commercial shafts that are spine rated for 40#-45# they will make a 40#-45#, 28" arrow with a 125 grain head.

 When you buy arrow shafts the spine value on them is for a 28" finished arrow with a 125gr head. For each inch over or under the 28" you subtract or add 5# of spine weight respectively. For each 25gr of tip weight over or under 125gr you subtract or add 5# of spine weight respectively.

I am pretty close to this also. I shoot a 55# bow and use 42# shafts with 125 grain heads.

Bare shaft test one before fletching at 10 yards. The pay attention to the nock kick as they explain and sand the center if you need to lower the spine
