Jon,
You have got to try an AL, man - all EB/MM necks are sweet, and the Albert Lee is no exception, but the overall guitar design in terms of ergonomics and balance simply can't be beat - in your lap or on a strap, these guitars are practically invisible! they're stealth axes!! uber-comfortable...
The neck (imho) is similar to an Axis, but without the asymetrical back carve - more a solid D shape... I switch very comfortably between my Axis necks and ALs without a thought... The Petrucci is a beautiful neck too, of course, but it's wider and thinner and definitely feels very different from either the Axis or AL...
Hope this helps,
Jim
