Jimmy, I'm sorry to say that I don't necessarily agree with our Capt. I have discovered over the years that frequent replacement of the countershaft sprocket, which rotates approx 3x to the driven sprocket's 1x, is one secret to longer chain and driven sprocket life. Generally speaking, I use three front sprockets to one rear (unsurprisingly), same chain. Naturally this is not always true, dependant on chain and sprocket quality, terrain and so on.

A 14T front sprocket will, all things being equal, wear a bit faster than a 15T as you would already know. As soon as a countershafter sprocket shows any sign of 'hooking' I replace it. Other benefits are a smoother and quieter ride.

Sorry if I'm preaching to the converted...
