For example, this is what i Pavel does in the 2nd video.
\/ = Pickstroke Up

And it seems weird for me, and this is the way i do it:

Notice that i start with an upstroke. What i wanted to know is, that if my method is bad, or is it limited for speed, this way is easier for me, but if its gonna limit my speed (which is what i want to achieve) id rather go for the other one. Any help? thanks.
