I was going on my 1st bear hunt and using a 50# tradbow with a 25in draw length and had some concerns. I read all of the grizzlystik site's info and called them to order. The lady I spoke with sounded like a salesman. There was never a test done with my DL and Poundage with posted results but it was obvious she was reading from a notebook to recommend an arrow. That would work with a compound because you have a lot of adjustments but lots of factors change arrow spine recommendations for a tradbow. I know my bow and what spine I could get to work with my tip weights, so I didn't take her recommendation and bought the spine I thought would work. Good thing because I had to use full shafts to make them work. Their suggestion wouldn't have been close to working with the tip weight I wanted. For the cost of the arrows, there wasn't anything magical about them to justify their cost. I feel the same about their broadheads. Anyway, here is a penetration test I did before my hunt.
Anyone ever do any kind of penetration test before. I’ve read the Ashby test years ago and keep going back to them. With my short draw length on a recurve I need all the help I can get. Got a bear hunt coming up so I been playing around. Seen a similar test with a barrel on leather wall. Figured...

Here is a video on how much pressure it takes to puncture hide with different broadheads.
I feel that grizzlystiks are good but over priced and hyped up for what they are. I switched back to axis. The Ashby forged head
https://www.grizzlystik.com/Ashby-315-Broadheadsbr-3-Pack-P1622.aspx has everything I'd like a broadhead to be except the price. It would be great for a high powered bow on an elephant, but for my slow tradbow the grizzly single bevels are plenty strong enough.
My thought on building an arrow is it has to be tuned for the bow. That arrow has to be flying straight, pushing all the force straight through the tip of the broadhead. Any wobble or kicking will lose energy that should be pushing through the tip. Next of importance is a cut on contact tip and broadhead that won't bend. Once it bends or breaks, you lose that straight push of energy. Then that broadhead has to be attached to the arrow just as secure and tough as the broadhead itself. Your system is as strong as the weakest link. If the arrow, insert, or broadhead breaks or bends, you lose that forward energy.
I use 150gr grizzly single-bevel glue on broadheads because the screw on heads use an aluminum screw-in adapter that I've had break in the past.

My finished arrow is about 25 3/4 long, weighing 600gr. I never checked the FOC. I'm not set on a specific FOC but I'm guessing its close to 20%. I recently chipped the side of the leg bone on a good size hog and the broadhead exited out the opposite arm pit at 20 yards. As he ran, the opposite leg slightly bent my steel broadhead adaptor. Only could tell from spinning it when I put it on a new arrow to use again. The front leg snapped my arrow and the rest of my arrow somehow worked its way back out. When I found him, 50 yards from the shot, the broadhead was almost completely worked out of the entry hole. He snapped the arrow at the shot. The tail end was right there. I did shoot through a palmetto that was up against him. I'm guessing he was lunging forward at the shot and the bone movement on my shaft stopped it from a complete pass though. But I had 2 holes. Can't complain about that. I'm very satisfied with this set up.
