@CosmicDebris:
Yes, you will be missing some things…although not HUGE things if I remember correctly (I mean, if you don't consider the defeat of the main villain and all the plot elements of Skypiea resolved huge). The Davy Back Fight doesn't have any important plot points. I can suggest that you read the rest of Skypiea in the manga. There are more HK subs available past 175, but I don't ever recommend those things anyway, you might create more plot holes for yourself. 
Oh I know, I love how they call Zoro Solon and Chopper is Jeob. I mean.. Jeob? WTF! and Upper Yard was like Upardo or something XD I did enjoy them though, I mean for the most part I understood what was going on but every so often I'd watch an episode and think, "Okay I can't wait to see the KF episode so this'll make sence…"
Basically I didn't want to be watching a Gerusama episode and then in the middle of it they have a flashback to Luffy defeating Eneru or something like that. I know he WILL beat him but I don't want to know how yet ^_^
So thanks, where's this MSN group?... and because I can't learn my lesson do you know where I can get HK episodes past 175? (Besides mIRC preferably)
