Carbon Handles
because an 100 Percent carbon fibre handle weighs less than one third of the weight of a cane handle the weight can be retain within the blade giving the bat a bigger profile.
Cane Handle
fitted with carbon fibre springs or titanium instead of cork or rubber
Gives a stiffer handle therefore less energy is lost when the bat makes contact is made with the ball
Similar effect to the 1970s steel spring handle.
I have a different theory and so do many pro players to your top thought on less weight in the handle I say more weight in the handle.
Many of the players we have supplied and do supply want heavier handles as it helps pick up with weight towards the hands a natural pivot or counter balance. It why quite a number of players use heavier bats than many think yet still pick up like a toothpick.
It not just low density that makes a bat massive yet light with added heavier handle it adds weight yet still picks up a treat.
As for carbon handles I used to swear by them but prefer cork ones today not sure why either
You can get natural variants in handle weight up to extra or minus 2.5oz
