I'm glad Petrucci is slimming down, even if just a bit. I feel like he got so big his playing suffered. Just talking out of my ass but I would think after a point your mass would just slow you down and make you that much less nimble/flexible on the guitar (plus like every super-shredder is pretty skinny), and watching him play some solos live around the 2010 era had him making more mistakes than ever in solos he usually breezed through. Then again, he could just be getting older and suffering the consequences at a coincidental time.
Also, I was going to right-click Petrucci in Firefox to add it to the dictionary and it recommended Firetruck as the word it thought I wanted. Oh man, so perfect.
