I'm new to traditional and am curious if I have picked the correct arrow. I have a Pearson cougar 64",40# @ 28". I draw 29" so I figure I'll be drawing around 42#.I made up some 1918's.They are 30.5" long. I put 4" feathers with as much right helical as I could with my blitz.The feathers are an 1.75" from the end of the nock. Is this ok? They weigh right at 500 grains with a 125 grain tip.I have about 300 aluminum arrows so If I need to use a different size its no problem. Any help would be greatly appreciated..Thank Roy
