I have been training exclusively DNF for the last 4 - 5 weeks. I felt like having a break from the fins. I find it really rewarding and fun.
The only instruction I have received has been watching videos. Mostly I just try to see what feels best and is most efficient by looking at the tiles on the bottom of the pool to see how much glide I can get out of a stroke.
I started off in this discipline just using a modification of breast stroke until I paid closer attention to some of the styles other people were using. So now it is - push of the wall with arms forward, glide, kick slightly before the stroke of the arms then glide with arms to the side, glide, bring arms forward, kick, glide with arms forward, then repeat.
My arm stroke is pretty much a fully stretched stroke but I see Will T. uses quite a different stroke for CNF with two distict phases - a) pull from top position down almost 90 degrees then the hands spin round so the fingers face the body and 'push' down in a swirling sort of motion. I am sure this is quite a simplified if not incorrect discription. I would love to have detailed discription of what he is actually doing. Hopefully I can attend one of his classes.
Haven't tried CNF yet.
