Great for modern defensive players, high control and wonderful speed for a defensive blade. I really liked the feel of the blade in my hand, the handle was perfect for chops. Only downside is the steep price tag, especially for a defensive blade which get banged around more I find.

That's nearly perfect for defenders. A bit top-heady, but I can play this blade quite well.
You can play very complanate with lots off control. Topspins and swats, too.
But when you're near to the table you have to play very focussed, 'cause the control ist not as good as far away from table.

This is the best blade i ever tried!

high quality 5 ply drive-looper's dream. If the surface is smaller, it could be a great offensive blade. Watch how Joo plays, this blade is truly designed for exactly his style.

truely that this blade isn't for every one, but when i tried this blade, it was slow when i chop, but when i put a bit power on the blade, the ball was just disappear when it come out of the blade, and of course my enemy lost that point :D

se nesesita una alta tecnica para poder cortar desde lejos tiene buen control al ser pesada da potencia y segun la goma que tengas
yo ahora uso una tenergy 64 y una feint 2 1.1 al ir mejorando se nesesita defender mas de lejos por los topspin del oponente y la feint 2 1.1 pierde potencia y llega muy por la red haciendo que nesesites un trajo mas fuerte para que llegue a la otra punta.
pero en lo personal prefiriria que sea un poco mas flexible y suave si tengo que puntuar la sin tener en cuenta mis gustos personales le doy un 9 la madera es rigida y dura no al extremo pero lo es
cambiare a una de puntos con espesor de 1.6 y vere que pasa

I didnt like this bat when I first tried it. But the more I used it the more it grew on me. The only thing I dont really care for is the handle. Kinda slick. I prefer the Defence 2 handle more. Great for chopping and looping. Will work as a classic or modern defence. Is somewhat heavy but I like a heavy blade. Bty says 100g. Also very expensive at close to $100.

the blade is good for choppers, mixing a little looping is also fine. overall, the blade is good but handle is quite small for me

I loved JSH ST. I gave an overall 8 because the blade is just way too heavy. I've tried 2 in the past, they were 108g and 103g. Well, you can use LP OX on one side to keep it light, but still a little too much after about an hour of chopping and looping.

This blade is very tricky, it is slow when using DHS H3 NEO, and fast when paired with a fast rubber.

For testing purposes, I used YinHe M2, 37 deg (I love M2 37, it's got a sticky surface and great speed) for FH, and Pogo LP OX for BH. Hitting and looping was a breeze. Since it is a heavy blade, there is no need to chop harder than just an easy/smooth BH chop.

Overall, this is an excellent choice for the choppers. I would use it if it is not so heavy.

Wow, I mean, just wow. Butterfly Joo Se Hyuk is one of the perfect blades for all Defenders. I paired this with a Donic Gallardo Sound, and a certain DHS pips (I don't remember the name) and brings out an extremely awesome feeling when you close up a point with a simple topspin drive stroke. It gives a smooth stroke to every chop you make, but you need to be picky for your corresponding rubbers. I recommend long pips, not short pips on this one.

It is no exaggeration to say that Joo Sae Hyuk blade is the ultimate blade for the defender if we take in to account the different models available in the market today from various brands. It is one of the best, if not the best, available today. It is hard and fast. It has practically no flex. It needs these properties to help the defender to attack or top spin when necessary. First let us look at the pimple rubbers part. It pairs very well with TSP Curl P 1 R 0.5 / 1.0 + long pimple rubber. Another popular choice of defenders, Feint Long II also matches well with this blade. Depending on the comfort level one should choose the fore hand rubber and the sponge thickness for the same. It is always better to start learning with the best rubbers in the business, the defender friendly tensor rubbers in near max sponge thickness. Andro Hexer and Tenergy series rubbers were found to be OK. This blade seems to excel in the long range defense when compared to its use in the short range or close to the table blocking. Joo Sae Hyuk is very good in generating low flat path cut balls or chops close to the table or from a distance on either the back hand or the fore hand. In this business this blade is simply great. Joo Sae Hyuk is not the best choice for the close to the table OX pimple blocking strategy. There are superior options for that. One can control the short game very well with the Joo Sae Hyuk blade and it is purely a matter of practice. It is certainly an improvement over the Diode blade in many ways. Diode itself was a great defensive blade. One just needs to find right rubbers for that. There are no warping issues with the JSH blade. This blade is very durable. It is a heavy and expensive blade. You would not regret the investment you made in this masterpiece once you master this weapon. Good luck!!
