Jon,
I've been shooting carbons like this for a long time- in fact, since the poltruded shaft days.
Not because I started out wanting a lot of weight up front- but I was tired of " one shot and you throw away" a wood or aluminum arrow.
So I tested carbons. Hogs are tough on shafts- and I wanted something they might not be able to break. Carbons were great for that, but lacked enough weight...it was like dry-firing my bow with the typical 125/145 grain broadhead set up.
So I started buying really stiff carbons- because the stiffer the shaft the more it weighed- and had to leave them full length and keep adding weight to the tip until it flew right.
Never cut carbon arrows unless they are too weak, cause that's the only way to stiffen them other than taking off weight at the front.
That's why I buy the stiffest shafts I can get, and start bringing the stiffness down with point weight.
I just shoot the pigs, wash the blood off, resharpen, and put them back in my quiver. Don't misunderstand- they still get broken sometimes, but it was a certainty with wood or aluminum- my record is nine pigs with one shaft...that's cost effectiveness there!
I learned a long time ago that successful bowhunting is the elimination of all mistakes- one way to make things less complicated is to shoot one bow for everything, and the same arrow setup. Switching bow weight/arrow combinations to suit a particular type of game is fraught with issues about relearning the path of the arrow, etc which I personally find difficult, so for that and perhaps a few other reasons I shoot the same bow weight and arrow set up whether I am squirrel hunting or moose hunting...and its worked out pretty good for me so far.
