Same here.
The 1 inch original is more foregiving than the magnum version.
In times way past, my go-to head was the 3-blade Muzzy.
But the 1 inch original Slick Trick is a 4-blade head with (I believe) more cutting edge than the Muzzy.
My thinking is this small 4-blade head has comparable cutting edge to some of the larger 2-blade mechanicals (which I simply do not like). Plus, with the 4-blade head, you're actually somewhat creating not just a some major cuts, but somewhat a "hole", like a large bullet "hole".
I know this "hole" is much the reason many "like" the Slick Trick Magnums,
but the "original" smaller one is what made the company famous.
Regardless what head you choose, so long as it's razor sharp, I believe shot placement is more important than which head you're using.
Not to be a Slick Trick history snob lol but I think the Magnum was the original sized cut. They came out with the smaller Standard sized cut to maximize penetration on large game and renamed the original "Magnum". Great broadheads no doubt.
