When we talk about ball RG's, we are talking about the low RG's. The high RG only comes into play when we reference the Differential (Diff), the difference between the low RG and the high RG. The lower the RG of a ball is, the easier it gets into a roll. The higher it is, the harder it has to work to get into a roll and the further it gets down the lane as it is working. Your three balls have low RG's of 2.48, 2.48, and 2.50 (BW). If you are speed/rev matched as you say you are, you could actually use a much wider variation in the RG's of your bowling balls.
I once wrote an article where I compared bowling balls to motor vehicles. The cores are the engines, and the surfaces are the tires. You currently have three dump trucks that you are trying to turn into race cars by putting racing tires on some of them. It really doesn't work! The balls that you have at home are also pretty low: 2.48 for the King Pin, and 2.52 for the Rhino.
I think that you have the same problem as one of the bowlers I first talked about in this thread. He is very uncomfortable moving in, yet he keeps buying low RG bowling balls. I'd love to see each of you try a ball with a low RG of 2.55-2.57. I think you'd be amazed at the difference.
