I started sea kayaking in the late 80's. I remember my first lesson on the 90 degree offset paddle. I was told to "learn how to use it" for the wind. I said, on that calm day in San Diego, "if it's that windy, I should be sailing." Sea kayaking gets very windy. I always hated the offset. I opted for a two piece, so I could be rebellious and set it to zero. Only in extremely, violent wind, and when I am completely exhausted, will I relent and set it to 90. I am still tarnished, among expert sea kayakers, for not priding myself on the offset skill.
Fast forward to first whitewater lesson, I was handed a paddle with a fixed 45 degree offset. Immediately I thought, "why is this paddle offset ... there must be some kind of "expert" whitewater technique that requires it." I hated it. Legacy dies hard, but some may actually like a steep offset.
Bought a new paddle... 12 degrees of freedom! Yahooo!
