DW20 all the way, he is the one who got me into modded minecraft, I was a vanilla purist and honestly thought it most mods were 'boring and overpowered' and had trouble and headaches with maps corrupting on me after months of work [seemingly randomly]. Then I randomly found one of his videos and I really could not see minecraft without that pack. It is balanced imo in terms of time/effort/energy and if i don't like the way a armor/item set effects the game, I learned to just not use it, however I think i got over that phase after I started to 'use' the armor that I thought was OP. Gravitational armor and Q-Set... They take alot of power to run, and can run out rather quickly if you depend upon the speed or jumping, or even flight [which I WISH thaumcraft would put flying carpets back in
]
Anyway, yes... the DW20 pack suits me because I like the arrangements of mods within them, the only mods missing imo are Ars magica and Mo' Creatures.
