as to alternate pickin and me i pretty much learned it when i started it was like the first thing my guitar teacher made me do when i learned lead. to me alt picking is quite rythm based in that its like strummng but ony one string. what i mean by this is my hand goes up and down at a predefined rate and then i choose to hit or not hit the string to create the rythm. if anything i find it easyish now cos i dont have to vary the rate my hand moves at, in fact i find using only down pickin harder.
saying that i dont really think about it, so i think i do often econimy pick, but not nearly as much as a should.
i would sugest learnin it, just play slow lead lines but use both up and down strokes, after a while it will become natural. also do what i did when i wanted to incease my speed, outlaw all legato, for a few weeks, ull find u'll get better, although it does leave me with a tendancy to not play enough leagato. :(
also i always find it wierd when people say alt pickin is anywhere as hard as sweeping which i have been trying to do for ages and am only just getting there. :eek:.
