I hear ya Dave...but I've got my own data, based on over 2 decades shooting white tails with 4 blades.....so I have to be honest with myself, and dance with the one that brought me.
Not meaning to diss anyone's findings, but I'm certainly not going to diss my own either. I've never hit a my side shoulder except in TX and I have a recovery rate of 36 yards with 4 blade Zwickeys here in GA.....Like I said, I've been shooting that head for over 2 decades, and I stop counting whitetails kills somewhere around fifty....back before there was an internet.
There's only one shoulder I'm worried about, and there's no gurantee any Bhead is going to 'crush it'....expecially spinning bucks that are spinning so fast they are rolling with the punch so to speak, and taking energy away from your arrow. Also, there is no garantee that if you hit the on side shoulder and do get through on one of them spinners, that you will get any vitals at those sever angles.
There's a lot of deer that you can pass through easily.....and the shoulder aint that big compared....and its not guarding much at certian algles either. I've done a good job of staying away from it, and my broad head has done a good job for me.....no, I'll say and exeptional job for me.
Yeah....TX Bottle Rockets may requier something else...but that's not a guarantee either....but I have my thoughts on my set up next year based on my findings of how consistanly they move inconsistantly and exatcly where I'll be aiming. Yeah, that sounds crazy, but I sure am tring to figure out my best odds, and I think I got a pretty good program for now on in TX. Wish me luck!
I'm sure you will stick to what you got confidence in.....and I wouldn't ask you not to. I've seen your posts here, and I sure wouldn't ask you to throw out your own data.
Oh....btw...didn't mean to derail the thread...
My favorite 2 blade Bhead at the moment is the Sasquatch....and 2nd is the ACE Superwhatever (the WIDE one)
