I have two Jenkins and a pair of Cavalier Elite's. I shoot 3-under but my Cavalier's are split finger. That's no problem at all.
The Cordovan seems to be more difficult to obtain these days. I tried to get some replacement leathers form y Elite's and couldn't do it a year ago. (Lancaster).
My favorite tab is the Cavalier. It is a bit more supple than the Jenkins. The Jenkins are very well put together though.
I know the Cavalier is salty, about twice the price of the Jenkins. But, I've been shooting the same Cavalier, with no change of leather, for four years. I shoot a lot. I don't use the chin rests or spacers because I shoot 3-finger under with index finger tip anchored at the corner of my mouth.
I typically trim all my tabs a bit to fit my finger length better.
Moving to a tab solved a sore finger problem I was having.
