My dd used a knuckle change for 7 years. The only way you could see the raised fingers was in a picture. No one in all that time looked like they identified the pitch and was sitting on it."The whole point in I/R and brush is to whip... the change should not have whip."
James, I'm going to argue that you may have that whip with a knuckle-change, and it's even desirable with that pitch. While many experts abhor the knuckle-change, a main advantage is that you can throw it full speed with arm-whip. It will not throw fast. So, while some would argue that the batter will see the raised fingers, I would argue an offsetting advantage is that full speed arm-whip release. And, if were not talking about D-1 or top elite travelball, I don't see all that many batters who are able to identify the raised fingers. While some hate it, the knuckle change is one of the easiest (maybe the easiest) change-up to throw.
