I have skied the
AC30 for a few years, along with several other ski's. It is my "go to" ski for ripping it up and suits me just fine all over the mountain. Steep trees, stomping drops, crud, deep powder, NO SPEED LIMIT. They are a tad stiff in tight bumps but nothing that you can't deal with, and I wouldn't sacrifice the flex because they rip at high speeds. A 177 or 184 will be fine, probably a 177 since you like the bumps and I really don't notice any difference between the two sizes at speed. If you are a great skier you will love them everywhere.
k2 aftershock , okay I'm not a K2 fan but was talked into trying the 2011 Aftershock in a 181, and now I am a fan, it was better than the AC 50 because it's a bit softer in the bumps and still rips in all areas. Soooo.. you may want to give it a try.
Blizzard 8.1, liked the AC 30 better and the Aftershock
Rosignals 82 ti, liked the AC 30 better and the Aftershock
Line prophet 100, fun ski, liked it a lot but overkill on the east coast and not as fun as the ac30 on hardpack but great all mountain ski,
Gotamas, love them too (skied on them for 6 days) , but obviously same as prophet 100 pro's and cons for east coast.
