This is a fantastic blade that allows you to play some really amazing shots with ease. It's made specially for Ma Lin's style, and that shows. I am reviewing the penhold version of this blade (the version that Ma Lin used).
Design: Ma Lin Extra Offensive is designed for playing penhold in the traditional Chinese style (close-to-table attacking and blocking). Shakehand players can still imitate this style -- there is a shakehand player at my club who plays extremely well with this blade -- but be aware that this blade was not designed for shakehand players.
Beginner players: Some people say that this blade is too fast for a beginner. I think this might be a little bit true -- it is pretty fast for a wood blade. But I think anyone can learn well with this blade if you put some slow tacky rubbers on it (I'd recommend Skyline 2 or Hurricane 3, unboosted). If you have experience in another racket sport, or you're at a level where you can keep a consistent rally going, this is a great blade to learn and play with.
Flick & Loop-kill: The place where this blade shines is the forehand flick and the forehand loop-kill. These strokes are so easy to play, and they're very effective at the club level because not many people play the traditional penhold style any more. Penholders will have a great time.
When to hit: Taking the ball right off the bounce is really easy with this blade -- even when looping underspin -- and taking such shots can be incredibly satisfying. You can take the ball at any time, but it's most advantageous to try to play the ball right off the bounce.
Backhand punch: The traditional penhold backhand punch is another place where this blade shines. It's very easy to redirect an opponent's smash and block it to an inconvenient location. This is because the blade has an amazing level of control. You can punch the ball really well with the reverse backhand stroke as well.
Feeling: The feeling of this blade is kind of funny. It doesn't feel like other wood blades, and it doesn't feel like carbon. If I had to describe it, it feels almost like it's hollow when you touch the ball. It gives a lot of feedback in terms of vibration, which some people like and others don't. Vibration is good for learning, though, which is why I think this blade can be good for beginners.
Spin: This blade can create spinny loops from brushing the ball, but they tend to be pretty slow. The low speed can give your opponent an opportunity to counterattack, which is not ideal. Brushing loops will produce a slow (but spinny) ball. Brushing shots are not so satisfying to play, and they leave you feeling like you mishit the ball. Beginners who learn to play with this blade will learn a lot of good techniques, but they will not learn how to play a brushing loop because brushing loops do not feel good.
Fast looping: If you want a fast loop, you need to engage the core of the blade and hit very quickly. This means that looping far from the table will have very low control, compared to other blades which let you hit fast loops with a slower stroke.
My style: I am not very agile and I don't have the best reaction time, but I am tall with a big wingspan, so I tend to play far from the table for a lot of my game. Because of this, the Ma Lin Extra Offensive does not suit my style so well. It's a shame, because I like everything else about this blade, and no other blade competes with this one in the close-to-table game. I played with Ma Lin Extra Offensive for a while and ended up switching to Nittaku Miyabi because of the far-from-table game.
Who should use this blade: Players (particularly penholders) who are agile and reactive enough to play close to the table should seriously consider this blade. Beginners who want to play a fast attack-based game should also consider this blade. Anyone who admires Ma Lin and wants to play like him should try this blade.
