I play the Fire Fall FC with the new design. This blade is awesome. If you like soft blades with not to much vibration the Fire Fall FC is very good for you!
The FFFC is a perfect blade for looping AND blocking. You can use the blade very variable. The blade gives you a great feeling with its softness. The blade is not fast as a ZX Gear In or ALC blades. But you have high control.
I play a heavy blade with 87g. Mainly the Fire Fall FC blades are around 80g.
