FIRE is the ultimate performance stick from Mercian; the top of the M-TEK range. It includes all the performance characteristics of the LAVA with an important and innovative improvement: Some players want a stiff stick to feel stiff, however some players want to protect themselves from the vibrations that can occur in a super-stiff stick. The innovative material in the FIRE dampens the vibrations, making a stiff stick that gives maximum energy transfer similar to a mid-specification composite.

Patented by HEAD in tennis, Mercian have a patent pending on the PISO-ELECTRIC fibres included at the bottom of the grip. These fibres are made from a material which has active molecules. The vibrations from hitting and receiving the ball move up the shaft until they hit the PISO-ELECTRIC fibres. This causes the molecules to vibrate, changing the energy of the vibrations into electricity and in this case heat. If a player was to hit a ball constantly for 24 hours, the area containing the fibres would heat up, but the quantity of energy converted is so low it does not create any immediate noticeable effect. If the material was connected to an electric circuit and there was a full shaft of PISO ELECTRIC fibre, a small bulb could be lit with the energy created!
