I'm using my RetroAchievements page to track my progress, and it's encouraged me to finally buckle down and try to beat R-2 for once. I optimized my team from Crystal the best I could (Tyranitar, Gengar, Suicune, Skarmory, Snorlax, Heracross) and it's been serving me better than expected! R-2 is still really hard, but not as bad as I feared :P
