I've only just begun Battle Frontier, man. I still have a long way to go.
Compared to what you've gone through, the BF and DPP eps will be a cinch.
From what I know/remember BF has some bad filler as always, but the battle episodes are the f***ing bomb and then you have DPP which has easily the best storytelling etc, so my guess is you'll get through DPP faster than you normally would any usual set of 191 eps >_>
