originally wanted to buy a G2Z but financials
and the fact that I already have 6P made me to
do this.

Basically I cut like 3 -ish inches long
bike inner tube and quad-folded it.
Then little parts that were sticking out
(the cut parts) are secured with 100mph tape
and the grip part is taped with thinly cut
100 mph tape for security.

Believe me I have tortured the grip to
see if it moves about but it hardly did.
