The index finger fulcrum is tried, tested, recommended, and like I said, used by hordes of drummers, plus taught by the absolute cream of teachers. So you can't sell it as the New Thing, Your New Thing.
So what to do? You can come up with another New Thing....and say the other thing produces no rebound....a little sad, and a wasted opportunity.

Not sure when you came to New york, or when you started drumming, or when you got really into hand technique, Casper...but there is a historical context that you seem to be unaware of. Let me try to explain...
About 15 years ago (I can't believe it's already been that long), Jim Chapin was still in very good health, and he was teaching private lessons in New York City about once per month. I was one of the people fortunate enough to study with him for a somewhat extended length of time. The very first thing he taught me was to get the index finger the heck out of the way and to use the middle finger as the fulcrum.
During this same period, Freddy Gruber was enjoying a resurgence in his career and fame by working as a "coach" to various legendary drummers - most notably Steve Smith, Dave Weckl, and Neil Peart. And what do you think he was teaching them? You got it - get the index finger the heck out of the way and use the middle finger as the fulcrum.
Up until this time, nearly everyone taught index finger fulcrum, and many of us had taken that to mean the index should be clamped tight like a vise! Obviously, we were wrong, and this caused us some problems. I personally developed pretty severe carpal tunnel syndrome. Greats like Weckl and Peart felt that it gave their drumming an overall stiffness that they were unhappy with.
So...a lot of people in the drumming community had misunderstood index finger fulcrum, and there was a large scale movement away from it altogether. Chapin was doing his private lessons and master classes, Freddy was lecturing to anyone who would listen, and Weckl was doing clinics on the stuff he was learning from Freddy...which he sincerely believed to be the holy grail! It was all pretty crazy. I was working at the Drummers Collective during that time, so I had a front row seat in the center of the whole thing. There was no way to avoid the middle finger fulcrum topic.
Of course, the error we all made was in thinking that we needed to eliminate the index finger completely to get the stick rebounding. In reality, all we needed to do was LOOSEN the index finger. We didn't realize that, so getting the index out of the way completely did give many of us a sense of rebound and relaxation that we had never experienced before. It even cleared up my carpal tunnel problems! Now...15 years later...I realize that rebound and relaxation can be achieved just fine with index finger fulcrum. In fact, I am currently revising my entire approach to be more based on index finger fulcrum again. For all we know, Weckl might be coming to the same realizations and making the same adjustments. I don't know. I'll tell you this, though - Weckl was not trying to sell anyone a bill of goods. That guy sincerely idolized Freddy Gruber, and he was thrilled to be learning something that gave his drumming a greater sense of looseness. And as I explained throughout this post, he was not alone. During that period, MANY drummers felt the same way about the issue of index finger fulcrum versus middle finger fulcrum...at least here in New York City. Weckl just happened to be the one who put it down on videotape.
I hope that gives you a clearer picture of what was going on at the time that Weckl formulated his ideas about middle finger fulcrum.
Continued luck with your own drumming.
