I was just curious as to what it might be like. There's one of each sitting in the storage basement at the local bowling alley. Not sure it's a pro or not, didn't get much chance to look at it. The lighting wasn't great, but the Rhino was green (or maybe teal) and the Angle looked green, could have been that old gray color. The guy running the counter said it'd be probably $10 per ball, then i'd have to find a place to get them plugged/drilled.
