Hypnotize is a solid pick — the main riff is a good workout for palm muting and keeping a steady right hand, though the tempo changes catch you out at first. Through the Fire and Flames is more of a long-term project than a quick learn, so I'd treat it as something to chip away at. If you want something in between, maybe look at some mid-tempo rock riff-driven tracks that let you practice clean chord changes without the shred pressure.
