I ain't sayin it can't be done, but I've never had much luck in learnin two styles at once.

If you're just learning I'd suggest frailing, although it's the opposite way from how I did it.

I'm just finding more results, faster.

Patrick Costello has some really good instructional videos on Youtube, here.

I've had really good results with these video's as I stated above.

Hope this is helpful.
