If you want to get into string skipping more, check out som licks and solos by Paul Gilbert especially during the Racer X (80-s) era.

I practice em pretty much. I really like the sound when playn´ some on small strings and than jump over to fat ones and so on. There aren´t no huge skipps on Erotomania solo though, I think it´s like 2-3 strings max, but some Gilbert stuff that I play have e-E jumps and they are pretty nice.
