Difference between Topspin and Loop

Hi Pingsklls, i've just search about loop in this forum and it seems there're many type of loop just like the basic loop, bird loop, loop kill, etc
just for sure, how to do all of them ? and what's the different between topspin ?
i know you said that loop is to put a lot of spin rather than speed and it seems like topspin off backspin stroke right ?
i've just try it and it make the ball go out, so what's the start - finiish position of this stroke to make a lot of spin and not go out
for the bird loop, i know how to do it, thats to use the other hand to raise up so it looks like a bird wings
for the loop kill, what type of loop it is ? i never heard and never see it
so, please tell me how to do all of loop stroke (if there're any type of loop again, please let me know :D)
anyway, the PingSkills Touch video, i see that when you do a topspin stroke in rally and at the last, it seems like you turned away your body (i also see you do this when you versus the italy)
this is it http://www.youtube.com/watch?v=8nvvQhPrxd0 at 1:12 minute

please for the answer :D thank you ^^

Hi Frendy,

As we have talked about in other forums, the topspin and loop are just extensions of the same thing.  All of the different types of loops you mention are also just variations.  Some have more spin and some have more speed.

This comes down to the angle of your swing and the type of contact you make on the ball.  The more horizontal the swing the faster the ball will go.  The finer the contact the more spin you will generate.

Don't get too caught up with names that have been put on all these strokes.  It is more about learning how to make the small adjustments for each type of ball and for each shot you want to make.
