The perfect arrow/broadhead combination?

I have read it but I have not drank the kool aid yet.

This is some really interesting stuff!!  Thanks Todd.  It's a tiny bit hard to wrap my mind around it since as a compound shooter for years it was arrow speed.  But I never fell into the lighter arrow crowd, so I was always trying to achieve good speed with a moderate weight arrow and broadhead combination.

How are those single bevel heads to sharpen?  I imagine they would be much easier??  

Thanks!

These are the high-end models.

These are the guys that I bought my stuff from.  I coudn't spring for the $80/3 broadheads, so I went with the next best option.  I got the 190 grain El Grande Grizzly heads.

I got some 300 spine ACC pro hunters and 100gr silver flames.........they seem pretty lethal

And I'm positive that they are.  I have, however, been stymied by that same thought process when an elk walked that never should have.  There's not one broadhead and arrow combination that won't kill an elk, but when the $#i+ hits the fan and things don't work out perfectly, then I want my equipment to be up to the task of making up for my mistake to the maximum extent possible.  Your combination would have been a better choice than what I had last year with the 3 blade 125 grain head.  I can't definitively say that this combination is better than yours, but the research results are in my favor, and that puts my mind at ease.

I talked with the guy who makes the grizzly sticks and he has a radically different idea of arrow flight than I do..........He likes 600-700 grain shafts at 220 fps I prefer speed...Im sure his stuff works great but I bet mine fly better at 50 yards. I still have over 80lbs of KE and arrow speed of 296 with a 460 grain arrow

I've read it several times over the years, and I finally decided to take a sip.  $48 total to try it out was worth it to me.  Plus, I'll be set if I ever get to go to Africa or grizzly hunting in Alaska.

A-MEN, nicely put

I could probably kill an elk with my pellet gun, but doesn't mean thats what I want to use.

TPI findings from Dr. Ashby's research
TPI of 0.62 unable to ever penetrate
TPI of 1.27 penetrated scapula +5-8" flesh
TPI of 1.50 penetrated scapula and broke offside ribs on pass-through every time

These results are from a zebra shoulder blade, and that should be close to a really big bull's size.

My TPI last year was the .526 that was in the first post: it failed miserably.
This year my TPI will be 1.814, and I'd bet a plug nickel that it would have killed that bull!

I'm really hoping that I don't have to find out, but if I ever do hit a shoulder again, then I think I'll be happy I switched.

Amen to that! This is great info. Im really glad I havent bought any broadheads yet. This sheds some great light.
as far as sharpening, this is just like my custom sushi knives. Japanese steel sharpend on one side only. I can see how it keeps rotation going and not only sharpens easier, but gets sharper too! If the steel is a proper mix, with the right heat treating the molecules are aligned perfectly for razor sharp, sharpening performance and density.

The answer to your question is yes, it does sharpen easier, but still great care and consistant angle play a major role.

Deep penetration in the right spot kills, and Ashby's results show that a "perfect" arrow penetrates better than a fast arrow. If an 200 fps arrow can't get there fast enough, then get closer...  

I spend more time sharpening a single bevel than a double bevel but I've been sharpening doubles for thirty-five years and singles only one year; I'm sure it'll get easier. But I may not want to go much faster because I'll say this; I've never been as scared of a sharp double bevel as I am of a sharp single bevel. They can be honed to a wicked sharp edge.

"They can be honed to a wicked sharp edge."  Ah the holy grail!!   

[HawkenBob]

My single edge sushi knives will literally shave you in one swipe. there above "wicked" sharp!

[Todd_ID]

The Grizzly heads I bought come ground to the right shape/angle, but they are not sharpened.  I haven't tried to sharpen one yet, but I think the Lansky is going to do a number on them.  If not, then the file and diamond ultra-fine stone should do the trick, hopefully.

Interesting. I would have to also find 300 grain field points. Or use my heavier tipped arrows which have an additional 50 grain weight and use 250 grain points.
