Good morning,
Reading this again...
This is no secret. To ski bumps well, it's all about practice. A he/she/it must simply spend a lot of time in the bumps to get to a point where you feel like you can ski them well.
Note: The day I started working on my bumps is the day I skied with Pinhed and did the double ejecto. It was f'ing embarassing.
I have much higher standards than that.
Technique? For sure! Foot speed? I'd go one further and just say you have to be quick. Quick with your hands, quick with flexion and your feet. I probably throw my tails around more than I should (Oh no, rotary!
), but then again I go for aggressive lines. Tourist bumps just don't interest me. For me, getting to where I am now with bumps was simply all about doing laps on Grouse Mountain. Practice, practice, practice.
I'll also add that looking way down the hill is way key in bumps. You don't "plan your line", just as HH says in "2". But keeping your head up and looking way ahead, it's really important. Otherwise, you end sideways into a snowboarder bump. Splat!
Be cool,
