Based on my interpretation of the events it is also very likely that you simply are not stropping adequately. Something to consider anyway.

I have a rule I follow. It's not really full-proof, but you might as well think about it. I believe that "what happens on the strop, stays on the strop". So, like Vegas, any damage you do on the strop, should be correctable with a strop. You know, "what happens in Vegas, stays in Vegas".

It's not always true, but, like Santa Clause, you have little to lose by believing.

I would try re-stropping and see if you can't correct some of the problem.

If you've done any damage the stropping should sound different than previously, particularly one side sounding different than the other. Otherwise, stropping may solve most of the problem.
