I need to get some arrows for my recuve and have been using Stu Millers Spine chart as a reference.
I am looking at the CE Heritage 250. My bow is Great Tree Ridgefire TD recurve 60" 45# @28". My draw lentgh is 28.5". I am shooting a 175gr broadhead.
From the collective knowledge, will these be over spined at .373? Is stu miller chart rather accurate?
Arrows are expensive and do not want the trial and error tuning process to get real epensive.
I think the 150's would be a better fit for you. I shoot a 54# Robertson Fatal with 150 up front and use 250's. My arrows are full lenght due to my draw. Stu's calc is a great tool, but only a tool. If you enter my specs in you will find my arrows to be at least 15-20 off on his scale, but they fly perfectly. Lots of variable play their parts.
I shoot almost an identical set up, but my bow is a Bear Grizzly recurve and not a take down. I don't know if that makes any difference or not?
My #48 pound Grizzly really likes carbon arrows in the .500 spine range with a 100gr. or 125gr. broadhead. If you intended to shoot a head that's 175gr. those shafts might work, but it's hard to say? I know that point weight will decrease the spine, but I found that I got too much flex when I went to a heavier point with the .500 spine. I kept decreasing the point wt. until I got perfect arrow flight and eventually settled on 100 grain Thunderhead broadheads.
I would have liked a bit heavier shaft and point weight, but I'm still at 8.5 grains per pound and my arrows shoot awesome. So I'm going to stick with that for awhile and see how it goes.
Don't know if that helps you or not, but this is just what works for me and my set up.
Stu's calculator is accurate IF you enter the correct parameters. Especially the center-cut entry. This is where most people miss it. If your bow manufacturer says that your bow is cut 3/16" past center that doesn't mean you enter 3/16" past center in the calculator. You MUST allow for the material that you are using for a strike/side plate on the bow. For instance, velcro is thicker than leather so it ain't gonna be the same. It makes a HUGE difference in the final results of what spine arrow to use.
Thanks for the feedback- I am also looking at the ICS hunters in the .400 and .500.
