Thanks for the great replies so far! In summary, it sounds like you guys like both but now considering my KE which might be a tad lower (260 FPS, 400 grain arrow, 58/59 lbs Helium....and yes 400 spine too as someone above asked). KE = 60 ft lbs I think?

Thus with KE 60 — would I be better off with the rage chisel tip 2” 2 blade slip cam style as opposed to the grim reaper 1 3/8” 3 blade — over the top style—as far as pass throughs are concerned and overall performance like field tips?

Note I think the hypodermics with the steeper blade angle would be tougher to get a pass through so sort of leaving that one out.

Thanks again to all

Just another thought—-before switching to the grim reaper 1 3/8” 2 years ago, I was using Slick Trick Mags 1 1/4” heads. I compared these ST heads side by side to the grim reapers and even though the difference in size is miniscule the grim reaper looks way way bigger.

I still have 6 ST mags so could always switch back.

I’m definitely no expert at mechanicals but believe the rage chisel tips use a “shock collar” instead of a rubber band which was an older design. Not sure how the shock collar works but it sounds better than a rubber band to retain the blades in the fly position.

I’m leaning now to making the switch to the rage slip cam chisels....still thinking.

Many thanks for all the great information. I'm thinking to call Grim Reaper today and see what they spec for KE on the 1 3/8. They must have test info. Time permitting, I'll call Rage as well for the same info on the 2" chisel and will report back here.

Thanks for all the 1st hand experience with these heads so far.

That last reply (thanks plecavalier) got me thinking about my old reliable ST Mags again. I'm now literally jammed between the Rage SC 2" 2 blade, because I believe they will use "less KE" to open than the GR and thus use more energy for the "pass through."

The other part of the jam here is going back to my old reliable ST Mags. They fly good and do some damage on impact.

Wowzer--read that 3x. I completely agree if all that concerned is penetration. In other words, and simply put, the best penetration would come from a needle like head or even a target arrow, but that would cause the least cutting damage to the animal. Maybe I should have emphasized --getting a pass through and causing the most damage to the animal. There is definitely going to be a balance there.

It seems like heads that cut the most--lose the most energy at a faster rate...therein is the "balance" of blade width to pass through probability.

Phew--that's a lot to think about.
