I'm curious, how many of you actually use your off-side roll on the river? I can do an offside roll in flatwater but when I flip on the river it's automatic to just go onside.
Also, does paddle blade offset affect the ease of an off-side roll?
The side I roll with depends on which way I rolled. If I flip to the left then I try to go with the onside (right). If I flip the the right then I try to go with the offside (left). That way, I am keeping my rolling momentum. Also, the direction I flip is usually the direction the current is coming from... it grabbed my edge enough to flip me... if I roll up on the other side then I am usually using the downstream current to get up.
If I am fighting to the death against flipping with a high brace then I don't have any rolling momentum when I finally go upside down so in that case I just go with whichever blade is already on top of the water. But fighting a flip to the death is a bad habit that I am trying to break... sometimes I think it is better to just tuck and go with it, avoid the high brace shoulder problems and get the roll over with more quickly.
Whichever side I go with first, if I miss it once or twice then I usually switch sides.
