You said it right there dude
KH has never truly been a shredder. Sure, he had some ok moments in his early career when he personally had more fire, but honestly he was never a virtuoso shred machine, especially against the fierce competition he had in their heyday from the mid 80's to early 90's. Its well documented he loves and was inspired by blues players such as Hendrix and Gary Moore, which is perfectly fine. Unforgiven solo is a masterpiece (thanks more to Bob Rock pushing Hamster to do it). At this point in your career and work ethic, stick to that formula and compliment the song. Nobody would hate on it. Diehard fans, especially fellow guitar players, by now know his limitations as a player and would welcome and probably enjoy more so a singing lead that was done tastefully and more importantly memorable.
I listened to this track my 4th time just now and his solo is just embarrassing. Those slides he does is just awful and does not fit the song at all.
