Wow, you must just runaround with a clover in your shoe or something huh?

Guess what! I used to shoot aluminums. 1916 X-7 blue, (long before the cobalt was re-intrroduced) and I shot them pretty well! Won a few State Championships, and even a World Title with those big old " honking heavy" things!
Switched to ACC' s. Amazingly, they flew just as good once tuned
] Won a few more...
Dropped off from competitive shooting for awhile, other than a few local 3D' s in the summer. Been four or five years now since I really did anything " big" . Next year I' m back at it however as I' m really missing it....
Built some Litespeed 500' s a couple months ago, threw a 3-60 uni and " G" nocks in the rear, and some 1.8 3D Durvanes, (blue of course
) fletched right helical, and threw a 100grain CB point up front. Got my new Max 3000 Omega cam bow, tuned it and the arrows, and guess what?! My scores have jumped up almost 10-12 points per game this year! 12, 11, and X counts are significantly higher also! How can this be??[
] I also easily qualified for the IBO Worlds, even tho I don' t shoot but once in a blue moon nowadays! Yep, carbon arrows sure do suck.....imagine that, I must be a true " wizard of tuning" or have extremely good luck also! LOL.[&:]

Sorry, I missed one of your posts way back, yes I agree with you---initially aluminum is straighter, no arguement. but they don' t STAY straight. If you have a straightener and like to diddle yes, you can keep them fairly consistent, but the problem is that the repeated bending and re-bending of them flexing and then being re-straightened on the straightener weakens the material and spine much quicker than carbon as carbon has much greater memory. You' ve been into the engineering field, so must know the flex tolerances of aluminum vs that of biased wrapped carbon fibers. Cyclic stress rates for aluminum are far below carbon.
I loved my old 1916 blues... another interesting point is that I used to shoot them at 70+ lbs! and I COULD. nowadays one cannot get a 1916 to spine out to anything over 52-55lbs, if they' re extremly lucky maybe 60. Hmmmm. Something fishy here also. Take a 1916 (or any aluminum for that matter) and find an older one of the same spine gradation. Give them a simple flex test---the older ones were much stronger. And it isn' t due to aging, they were rugged enough to shoot perfectly out of my High Country Supreme at 27" arrow (29" DL) and I think 72lbs when new. I really need to dig up some old charts to see what they were rated for back then, but I know it was much more than what we see today. More fuel to add to this fire, hehe
Good shooting, Pinwheel 12
