I think the best HM guitar payer is Marty Friedman, Megadeth is nothing without this guy
n the best "creater" is Vai n Van Halen
the best in "melody" n little bit "strange" style is Paul Gilbert (n Richie Sambora too? perhaps)
n lastly best in HM-Progressive is Criss Oliva (i dont kno ecxactly the name but this guy's from Savatage)
