BubbaD, I understand your point but I do the opposite for the same reason.
When I shoot a 10 pin, I break my wrist, and shoot a full roller with a spare ball to get a near staight shot.
I don't want my muscle memory to kick-in for my normal shot so I make everything different, no finger grips in the spare ball, take off my wrist brace, the ball is even a different weight. When I pick up my spare ball to shoot a 10 or 6-10 ten, it is a whole different shot, that is mentally seperated from the feel I am trying to achieve on my strike ball. To make it a golf analogy, shooting the 10 pin is putting, the strike shot is my drive, and the muscle memory and protocal are completely different for each.
This works for ME and and though I am not a great bowler converting 10 pins at an above average pace is my best bowling skill. My personnal theory would be if you are trying to pick up your corner pins using the exact same stroke and release as your strike ball make the FEEL of the spare ball the same by duplicating weight and grips. If you are using a release on your corner pin shot that you don't want to repeat with your strike ball, make the feel distinctly different.
Joel, you can take, my opinion as the, some people get away with it method. I will be interested to see what the coaches have to say about this. Is there a preferred way to setup a spare bowl or is this a matter of what feels right for each inidividual?
