I have a lefty Morningstar on order, something in the mid 50s at 26". I have been shooting 1918s with 160 grain broadheads, with glue-in bh adapters out of my 52 at 26" right hand Robertson and my favorite yew/bamboo 57 pound bow. For my right hand 53 pound yew I use either 1818s with glue-ins and 145 grain Grizzlies or 1918s with the screw in adapters and 160 grain broadheads, which gives me 200 grains up front. All of my broadhead arrows are 27" bop, I am not going to change that. I have a dozen 27" bop 48 pound tapered cedars with the 145 grain Grizzlies. I have a dozen 53-55 pound tapered cedars with 160 up front that fly out of everything except my heavier robertson. I need to make some practice shafts that match these various broadhead hunting arrows, and I am trying to decide which arrow should be my go to arrow for the upcoming shoot it until its worn out Berry Morningstar. The cart is out in front of the horse, but any good bow will tolerate some various spines and I need to make something. Should I make target 1918s or get me a bunch of tapered cedars? I am assuming that James will hit real close to that 55 pound mark, but I don't know exactly what the spine tendencies for the Morningstar will be compared to the bows I have. All of my bows are cut 1/8" from center plus the leather.
