LaBrie is capable for a LOT nowadays. He just matured, a lot. If you'll look through some videos, you can see him hitting G5s/G#5s/A5s at 2005-2008, but he doesn't do it as much because it's pointless and it's hard work I guess.
Also, he nails everything DT plays...Pull Me Under sounds great, Take the Time sounded great till 2007 then for some reason Mike thought they should stop playing the 2nd bridge there. Same for Voices, check out live versions of those songs at 2007/2008. Surrounded doesn't sound that bad, James usually nails most of the notes in that song. Another Day sounded the best at 2007 since James' vocal rupture...you can't say he's not doing well for his age.
