Have you personally gone from a 53-39 to a 50-36. Why and have you benefited from this change?
maybe you miss the 53-39 and fell for all the hype?

I currently run a 52-39 on a 12-25

For years I had run 52-42 on a 12-23 or an 11-23 or even a 14-25.

Surely it makes sense to have a 5036 on a 11-23?
