Who has the Fastest loop?

That's a tough question.  All the world-class players have pretty powerful and fast topspin loops.  Having said that, I agree about Ma Long.  He has a very powerful loop but it's a potent mix of spin and speed and not necessarily blistering speed.

Ryu Seung Min (especially in the early days before the speed glue ban) had arguably the most dangerous forehand in table tennis and was probably as fast as anyone I've seen.

Ma Lin's forehand attack off the short ball is also blisteringly fast.

Personally, from the little I've seen of him play, I was also really impressed by Segun Toriola's attacking forehand.

I didn't vote for Ma Long to have the fastest loop but, of all the professional players, if I could steal the forehand of anyone, it would probably be Ma Long.  I just love his smooth flowing motion and large swing.  That's definitely the stroke I try to emulate.

While it's hard for me to say who has the fastest loop, I can think of a few prominent examples of players who definitely DON'T have the fastest loop.  Two that come to mind are Timo Boll and Jun Mizutani.  Both are fantastic players and I love watching them play, but their forehand seem to me to be more spin and control rather than pace.

ill go for ma long

Ma Lin has a GIGANTIC swing & he MURDERS his topspins!

Ma long has the fastest LOOP and

Hard question huh there are many great players out there Jun Muzatani, Vladimir Samsonov, Michael Maze, Ma long and many others can't decide. I just love watching them. I have seen Simon Gerada do some amazing crazy spins too he is a great Aussie player. Too hard to decide too many good players out there. 

okay i think this question is quite hard to answer. who knows? maybe there is a weightlifter who plays amateur and perhaps he hits the ball faster than all the world champions?

Alois you have made a good point it is not pure strenght that makes a fast hard hit winner. Merv Crowley told me about 8-9 years ago the same thing, he said just move your wrist and swing faster. He said timing and technique was the key. Merv said he learnt this when he did his coahing course.

True...but there are millions of players around the world and maybe one or two are strong and have good technique, but we never heard of them. Can that happen?

I mean for example Simon Gerada has a pretty good forehand, and perhaps nearly as good as Ma Long but I am pretty sure there are many more people who know about Ma Long than Simon Gerada.

Yes Simon has a fantastic loop on his forehand but his backhand is very good too. Simon believes in himself and trusts his own ability, that goes a long way to being a good player. But most of all Simon Gerda is a really nice person and he has the perfect attitude for a sport like table tennis.

Okay... According to Wang Tao, Wang Hao has the best forehand in the chinese team. 

I say scalger you can't even see his hand when he plays

Hard to say Ovtcharov has a good fast loop. Jun Muzitani ? Werner Schlager? Timo Boll? Jian jike. There are too many to mention as there are a lot of fantastic players out there.

Zhang jike and ma long have good loops
