They don't have any real weakness as compared to the average player. Just listen to them play. Sure they'll say 'I have a harder time with X and Y' but that doesn't mean they do X weakly, as a matter of fact, most of the time they excel at whatever X is.

And again, if you want to go on PURE speed i.e. legato and alt picking whatever--Wylde still does not make the cut. A legato run from Paul Gilbert versus one from Zakk Wylde is a lot faster. The reason why I discounted Zakk Wylde is that he uses legato to keep the flow going, which gives his lines the appearance all being played at an even tempo with the same note durations when they are not. That's all.

And aschleman, no one is forcing you to read or post to this particular thread, why insult it?
