question about these nitro tanks

[Ter-Me-Nate]

can anybody tell me hw i can get the weight of these tanks

aci bulldog 2 68ci 4500 crabon fiber

and crossfire 68ci 4500 carbon fiber

which is lighter

because i already have a bulldog 2 but, it seems to be heaver than me friends "smarts parts 88ci 4500 fiber wrap adjustable"

mabye its just me but if a crossfire is lighter i may go with it

Regardless of weight, The Crossfire tanks are better, better recharge rate and better consistency than the ACI tanks. Neither should really be lighter, if they're both fiber-wrapped tanks. Adn differences in regulator weight should really be negligible.
