This is my personal opinion so don't take it as absolute proof//
I think that the S.W.E Shift is a great shift, but very impractical for the real world. If you get to the point of Chris Kenner then you could possibly perform it. However, there is many more proficient card shifts which will suit the effect you're performing, and your crowd situation.
Take the time to learn it if you wish, but it's a very difficult move.
