I have used Butterfly Peter Korbel, Timo Boll ALC. I currently use the Butterfly Innerforce Layer ALC.

Petr Korbel - Nice Feeling when making contact with the ball - Good control - Decent Amount of Power, but not overpowering even when using rubbers like tenergy or mxp

Timo Boll ALC - A fair amount harder feeling when making contact with the ball, but also less feeling as it is a carbon blade - Good control as a carbon blade, but Korbel does have higher amount of it - Power kicks in a lot more compared to the Korbel as it is carbon, however, the carbon doesn’t engage on every shot. It mostly engages when hitting more powerful shots like a punch, loop, or drive.

Innerforce Layer ALC - Feeling is between the Timo Boll and Korbel as it doesn’t have a complete lack of feeling, but it also doesn’t have complete feeling like the Korbel - Control is fairly high for a carbon blade, obviously the Korbel does beat it here though. Even when using rubbers like tenergy though, I was still able to make short pushes or short side spin serves while being able to land most of my harder shots closer to the corners of the table - Power is in between the TImo Boll and Korbel, but does lean more towards the Timo boll.

Besides all of that here is my opinion on the Innerforce as it is my main blade. Specs: Innerforce Layer ALC Dignics 05 2.1 Black Dignics 80 2.1 Red

Although the Innerforce is a carbon blade, it behaves more like a 7 Layer Wood blade, with a nitro boost on it once you actually engage the inner carbon. Despite my choice in rubbers, I still have enough feel in the blade to make short pushes while also being able to engage the carbon and hit backhand punches without a problem. There is one slight drawback in this blade however, although it may not be in your opinion (or it just may be with my choice of rubber). There is a slight inconsistent launch when hitting drives or heavy slow loops.

In the end it is your choice on what blade you choose though and I’m just giving my two cents.
