Absolutely no idea if this thread is still relevant or should be shut down (wouldn't mind starting a new one myself); but I'm considering running Modest with 192 HP/252 SpA/64 Spd as opposed to 236 HP/252 SpA/20 Spe. It's HP only goes down by 11 -- actually conveniently getting to the odd 347 -- and in return it speed creeps 68 Spd neutral Heatran as well as this lot
