I certainly vary my stance a lot - sometimes on launch and when on a longer board, mid ride. But... you say your home break is left and you surf that frontside ? - so I have to assume you stand goofy footed then? If you are used to having either stance... then go for it - I think this gives you more variety to your ride experience - even though, every wave is different!

Hmmm.. interesting observation. I am going to be watching others now. I do know that I vary back/frontside on smaller waves.... but once they get to a certain height... I dont like to have my "back to the wall" if I can help it. No reason, just feel more in control - regardless of what stance I am in.One more point - I think the stance you start off with - can depend on what side you find yourself paddling in on. Left side... drop the left leg back - right side, right leg back. Maybe?

I surf natural, but used to skateboard goofy up until the mid 90's. I started switchfooting on sup coz it was easier to paddle into waves. But I switch back to natural stance just before I go for a floater or the wave is going to shut down heavily. I'm now switch footing a lot on my longboard simply coz its fun
