I'm working on a replacement clubhead for the senior longdrive club
that I've been selling and would like your opinions. It's tied in to
the article Bernie wrote for me about a year ago. (article here

I can get a nice cast head done up 193g or so to allow for a longer
club (47"ish) and I can do either conforming or non-conforming.
Since the goal is to help seniors and other golfers with slow swing
speeds pick up a few yards, do you think that it's important to have
a conforming head? Or is non-conforming hi-cor OK?
I'm questioning whether the distance increases for slower swingspeed
players with a non-conforming head (a few yards?) would be worth
alienating those that won't play anything non-conforming.
John,
There isn't enough info to either check the idea nor answer your
question. A couple of vital facts are missing:
* Loft
* COR for the illegal design
I ran a few trajectories with TrajectoWare Drive. I used a loft of
14*. (If this is for slow-swinging seniors who can get up to maybe
80mph with a boost from a longer shaft or at least a light weight),
then 14* is about the right loft. I assumed (probably contrary to
fact) that the illegal version has a COR of 0.90 (as opposed to the
legal 0.83).
With those numbers, I see an 11yd difference between the conforming
and non-conforming driver. Of course, I have no idea what COR you
have in mind for a non-conforming driver, so my numbers may have
nothing to do with realithy.
Good luck!
