yup! agreed the top part is the heavy one..
the top part itself is heavier than the casing plus the ballast and tubes!
i believe he is already sourcing for a lighter alternative like acrylic...
dats wat he told me.. the overall weight is worrying..
and yah like dr evil mentioned theres nt much air ventilation..
but this is his prototype mah.. confirm gt alot of things to improve on..
nw just waiting for him to be free to do the modifications..
