Which kinda loop motion is best?

it all depends in your style and what works best for you.

Thats not true, and there is no reason why it would be.  Style is define by choices a person makes...but they still remain in the laws of physics.

I think it is best to just enjoy the game and keep it simple. No offense implied but unless your a world ranked player, you wouldn't need to worry about such technical aspects of the game.

Kreanga vs Samsonov, who has the 'best' loop, they bothe destroy a ball evenly, its what they do to create the opportunity in a match situation than matters. ALL top players in the world have an equally efficient f/hand loopdrive/kill, there really is no difference, they will all put the ball away equally as efficient given the chance. It's the other stuff that stands them out. +1 < id="gwProxy" ="">< ="jsCall();" id="jsProxy" ="">

Although, i agree there maybe exception, we call all agree that even a monkey's body to an extent is very similar to human...considering such broad notions...I never even got into using parts of body coz I remember that brought out trouble.  I am strictly concerned with how the blade touches the ball for right now.  Besides, Anton, I am having an extremely hard difficulty imagining a player(again, lets set exceptions aside) for whom the fundamentals will be reconsider.  I see your logic, but I am not sure how much the little differences among each other changes much.  Perhaps an example will shut me up.

I still don't believe any pros ever do a convex loop. The Samsonov video of him doing a backhand loop I don't believe was convex, it's just the curve of looking at the swing from a higher angle, making it look convex.

I use a concave loop for my backhand, and straight angle for my forehand loop, but maybe straight is better for backhand too, I'm not certain.

I believe concave loops make more spin but sacrifice speed.

I've only recently started adding sidespin curve on my loops but I'm only doing it to force the ball to land where I'll be waiting with a more powerful straight loop to kill the point on the next shot. Either that or to help curve the ball off court and away from the opponent so he can't chase it down. I think this added dimension to the looping game is what seperates the really highly rated guys from the good club club and really I figured it out too late in my life :p.

The curved loops are much more difficult to use as a general attacking shot so I'm only hitting straight loops most of the time since I can put much more pace on those. I don't think it's important to be able to curve them both ways at the level I play but it's just something to practice and keep the mind going

I think the Straight one is more consistent and more reliable. If you loop differently I think you can change the arc of your loops, changing the amount the topspin jumps up or forward creating variety.

Also from protabletennis.net
"In the case of any stroke where an arc is used we can have a positive or negative arc (Diagram I). The positive arc follows the outgoing trajectory of the ball much more closely and as a result has a higher safety margin. The negative arc places much higher demands on exact timing. However in the case of the loop against a backspin ball where the racket angle is much more open the advantages or disadvantages are not so critical.

Many players think that it�s safer and more natural to have a negative arc with the BH topspin and especially where the feet are more parallel with the end of the table. However for those who want to work with the �tennis� BH it�s important that they have the same positive arc on both wings and don�t need to change from one to the other."

In general, concave loop does create more spin coz less ball is touched if you the contact with the lower/middle region of the paddle.  But if you let the ball fall, then do a straight motion loop...the arm speed is faster, if you hit the ball with the tip of the racket, there is more torque, and since you are touching less of the ball, it is much easier to apply momentum on it.

Once it is invented then everyone will see that it is the best. Yep, definitely the S-shaped (or Z-shaped) loop I have decided it in my head so it must be true.   I had a dream last night and they could hit it really hard using an S-shaped (or Z-shaped) loop and the local Butterfly dealer had mixed up their order and sent them 2 sheets of tackiness chop on a Defence Alpha blade instead of the 2 Tenergys on a Schlager carbon and they could still hit the ball hard.

wiggy, oh yeah? i have lots of polygon loops! decagon, hexagon, heptagon, square and even nanogon shaped loops! 

its a 9-angled style loop nyahahaha, its nonagon btw my mistake

speaking of that wiggy, i also think its also possible to produce obtuse, isosceles and equilateral triangle loops  nyahahaha

aw, i didnt know pythagoras plays pingpong too 

and his rubber symbol is PI hehehe
