the only reason eddy is considered revolutionary is because he got there first. maybe if ozzy was thrown out of black sabbath earlier, rhoads may have been first. rhoads developed his style on his own, and did not copy from eddy. as guitarists i'd say they're pretty much equal.
To improve technique and of course trying to keep all as clean as possible. I know my own limits and speed limits and so on I never play anything I'm not capable of. That wouldn't make any sense. After three years of playing I tried to play everything as fast as possible and that sounded, I would say, like shit, and I didn't realize that if I'd play bit slower things than I was capable of playing then everything would sound much better.
