The continuous tapered arrow

[cjgregory]

I enjoy targets and 3D  almost  as much as hunting.
I prefer an arrow around 600 gr. so the Arrow Dynamics shaft is out.  
I have been looking at the grizzlyStik for a while now.  Plus it's a continuous taper most of the way through the shaft.  
It's not a new technology of course but I only want to shoot one shaft.  I don't mind the price as this and writing are my passions and it's better than wasting my money on a new vehicle or drinking beer.
Who has had some really good experience with tapered shafts around 600 gr. and heavier on the 3D range or even indoor?  I want to hear about your experiences.  

Presently I shoot accurately to 40-45 yards with 2219s fletched or no fletching.

My AD Trad's with a 175 gr. point weigh right at 565 grs.,I bet a AD Trad Hammerhead would put you at the 600 gr. range depending on the point weight.you may also want to look at Carbon Tech,they have some tapered carbon arrows.

3Rivers has test shafts, on their website.

I think the AD heavyweights are 500 grain for a bareshaft, I've shot them but don't have any exprience with them on the 3D range.  Just getting into shooting Carbon Tech tapered Panther shafts.  I like those much better than the AD shafts because they fly flatter and still hit hard. dino
