a side by side comparison, just for kicks!
the Reaction has more rocker, length, and volume. The Transition in this photo is my old one (now owned by a friend). It is a bit over 10' long. Having paddled both, I think the Reaction is easier to paddle and handles with more predictability. They roll about the same and the cockpits sizes are almost identical.
The feel like they are the same speed on flat water, but the Reaction feels faster in whitwater because of a drier ride (probably a result of more rocker and volume)
