I just completed my NG+ on Persona 4 Golden. My clock is at 145hr+ and I still didn't get all the trophies. I should've read the list first, I probably could've gotten Hardcore Risette Fan quite easily, but I power-levelled at the beginning and wound up doing most of the game with a level 99 Futsunushi :p Which means Rise's comments are only along the lines of "It's puny! Use ice on it", "That one's easy, use fire" and none of the other end of the scale (the trophy is to hear 250 different lines from Rise during battle, in one playthrough).
It was great the second time through, I'm actually glad I failed to max out Marie and my compendium the first time, that meant a whole new dungeon and also a new boss on my second play.
Still undecided as to whether I should give it one more run through for those last couple of trophies or move on to P3P
