Query: Best of recent model revisions and still the best stability shoe

After wearing out two pairs of the Kayano XII I was fortunate to find available a pair of the discontinued XI. The XI is far superior as a stability shoe than the new revision. I've worn Kayano since the begining and have found that about every third or fourth version falls short of the characteristics that made this model famous. It is durable, stable and has a nice feel. Now, the XI can be found at significant discount. The XI is one of the best Asics has made and the XII is probably the worst. The XII is much lighter, but less of a stability shoe and certainly not durable and not made for a heavy runner. I hope that the XIII is more like the XI and less like the XII. You should stock up on the XI while they are still available.
