Where do the legs go?

One of the things about dragonboat that has been baffling me is legs placement. I see different people do it differently depending on individual preference. So in order to know my preference, I need to know my paddling style and how my body works while paddling.

Since I started paddling last year, I put my left leg forward and right leg back ( I'm a left paddler). And then as time passes and I start to twist my body more, my stomach tends to meet my left leg and sort of obstructs my body from dropping lower during the dip. Or maybe I'm trying to push my bodyweight down more in the dip. Whatever it is, I find the position of my left leg forward causing some issue. 

So at yesterday's session, I switched legs. Right leg forward and left leg back. It felt a bit weird and somehow more tiring for my body, so am not really sure if I'm doing it right. It certainly feels easier to twist and drop my bodyweight forward though. The only way to know is by trial and error in the next coming sessions.
