I've tried both 37/40 and 40/37. The 40/37 has a bit more speed but harder to impact power, and they seem well suited to outer ALC blades, putting them on inner ALC doesn't feel as good.
I also agree that the pros' rubbers have much higher hardness than the market versions, because we don't have the techniques for it.
Heming Hu said so himself on this forum, that his sponsored H3 39.5degrees are as hard as the 41degrees on the market.
answering @khongbietgiainen: Even Heming...
IMO the blades the pros use have the same composition as the blades we use, just the quality of the wood will be very high and the blade weight is precise. It doesn't make sense if they pros' blades have different type of wood or carbon, right ? So for us mortals, we don't really need that much...
the moral of the video is that just chose whatever blade that make you feel comfortable, but I wonder, although ZJK said that he used only normal looking blade, but is his Viscaria really normal or they are custom made ?
it's my own opinion though, my looping style is more hitting than brushing so I prefer stronger sponge. And I think that H3 has superior sponge, especially #22 blue sponge, many other brands are trying to imitate that blue sponge but didn't come close.
when I loop far from table and counter looping which engages the sponge more, I feel that the ball lacks speed and stability compare to H3, not by much, but able to tell
the problems with all other H3 alternatives, IMO, is the lack of support from the sponge when hitting hard. They all are easier to play than H3, but only for light strokes and brushing loops
sorry I mistook the Green LAC and the LAC Pro, my friend broke the Green LAC in 2 weeks, then switched to the Pro and it's still good after 4 weeks.
Both 3 versions play exactly the same. So I guess the LAC Pro has the strongest bond in my case.
its cake sponge is really good actually. there is a Blue sponge version of LAC but @Grumms said that it does not play similar so I guess that sponge is not good
My friend is playing the Green package LAC, I tried to tear the sponge from the topsheet and found out that its bond is stronger than...
G09c is very good actually, I can still pull good shots with it. The slow speed and high control is a good thing, It will helps you to develop your power generation. Although the durability is not so good, my sheet lost all tackiness in 1.5 months
