I shoot 3 under and like the Widow tabs too, but my favorite is the Eagles Flight tabs with the "O" ring for your finger. That is really comfy on your finger.
I made myself a couple of the Widow Tabs out of Cordovan that I got from a member here a couple years ago and they work fine. I have also made a few different tab designs to try too. I will find some leather at a rummage sale or flea market and make a few tabs to try.
As for those Safari Tuff tabs, they really look great, but I can tell that I would HATE that string on my finger. I like the velcro strap on the Widow tabs or the "O" ring style. If there were a way to add an "O" ring to that Safari Tuff tab, I'd be there for sure. No doubt about it.
Get you some cordovan and experiment. You'll be amazed at how well you'll like them and how well they'll feel to you. I know I was.
Besides, it's kinda entertaining to make your own gear.
