Has anyone used them? Do they work well if you're slightly overspined or want more FOC?

Yes they work,and extremely well I might add

Terry

Thx, Terry!

Yes they do!

How much longer do they make the arrows?

Depends on the weight. I have all weights in stock and can measure them all if needed. I would guess from about 3/4" for the 75 grain to 1 1/4" for the heaviest.

I have "almost" tried them several times but hesitate with the thought that there may be a tendency for the arrow to shear at the base of the weight.

Just the extra length alone would lower the arrows dynamic spine.

They are a fantastic component. I love them and have used from 75gr up to 150gr.
I recommend using Quick stick hot melt glue, and clean them well,,,they are too expensive to lose in a target.

....as opposed to the arrow shearing at the base of the head? There is no difference.

I use them all the time and and they work well.  It has been my experience you don't need to go up as much in spine as you might initially think either.

My goal is higher overall arrow mass coupled with high FOC and the Woody Weights help me get there.

Why not just go to heavier broadheads?

Well, I think there could be a difference.  The heavier the broadhead or point, the more is the tendency for an arrow to shear at that joint.  At least that is what crossed my mind.  OTOH, adding a WW with my 190 heads could be a great way to up FOC.  not so concerned about hits on game as with glancing hits on hard ground, stumps, etc.

I am using 75gr woodyweights and a 190gr cutthroat on 80-85# doug fir shaft 29"BOP) this year for elk hunting. The fly great out of my 55# Maddog Mountaineer drawn to 27.5".

Using the 200 grain Woodyweight with the 160 grain blunt / broadhead, I'm using them on 30" 125/135# shafts out of my 75# Hill Wesley Special. They fly nicely. I'm hoping to kill a buffalo with the set-up. The arrows weigh 1120 grains or so.

Just over a year ago, I gripped the silent double-barrelled .500 Nitro Express and watched spellbound as my mate, Alex, stalked his way to ten metres from a buffalo cow and sunk a heavy wooden arrow right through her chest, using his heavy Black Widow longbow. The buffalo only made fifty or so metres. He used Woodyweights, and happens to be a bit of a guru with them.

Im using 150 gr woodyweight with 140 gr grizzly broadhead on Surewood shafts, out of a 43lb Maddog bow. Arrow weight is averaging 685gr, with between 21-22% FOC. Opposite side shoulder blades or leg bones do not worry me... I pray for a quartering away shot on whitetails.
