Ah! You're talking about just the fingergrooves!
Ohhhhkay. If you restrict them to the forward area of the grip and leave the back 1/3rd of the total length plain, you MIGHT get something that appeals to all tastes. For "delicate work" of any sort you'd get better "fine control" by choking up on the grooves but for major smashing, move back to the full swell as at present?
That could REALLY work well.
Steven, how much does the pinkie loss affect the handling of the current models? In experimenting with mine, it seems that the "upper tip" to the pommel swell goes into a funky place on my palm when I pretend I've got three fingers. At a guess, polishing down the "upper tip" of the pommel swell while leaving the lower swell intact should give you a reasonable traditional-type grip without going to fingergrooves?
Just a thought...reminds me of Mick Doohan's race bike; the guy's the fastest in the world today but his rear brake is a thumblever on the left handlebar due to extreme damage on the right foot where the rear brake usually is. And he's STILL the best on the planet, racing for team Honda in the 500GP.
Adaptations are possible! If that means fingergrooves, cool.
