Too stubby is the Taito Crazy Climber sticks.
They were basically a ball that stuck out of the CP.
If you gripped the ball over the top, like you would any other game, you'd end up with calluses on your knuckles.
You should be fine routed, or not.
I've done both, and been fine.
It's more a choice of feel than anything.
I personally hate it when there's too much stick above the CP.
