What are your goals with re gearing? It sounds like you want more acceleration? It was hard to beat the 19/43 (2.26)combination in the edge chassis. If you need more snap, you should look to your clutching.
Going to 23/41 (1.78) would be the exact opposite of what you would want to do. That would be some incredible top speed if you are flat land lake racing

, but won't do much for you in the mountains. I guess I'm making some assumptions here as I don't know where you ride or what sled you have. Hope that helps though.
