Gearbox shells....?

I am now looking for a good reinforced gearbox shells good for rof and high fps, like around 400. I thought about a gearbox like this:

Modify Reinforced 8MM gearbox, I'm just wondering if these would fit the custom Chrome Moly gearset and also not tear up as easy. I've got alot of upgrades including these gears with a 120 spring and Matrix turbo. So this is going to put alot of stress on the gearbox shell. I figured a Tokyo Marui V2 reg shell probably would crack after alot of use, just wondering if anyone has a opinion in a good, reliable reinforced V2 gearbox shell

thanks


::EDIT:: If anyone can put it out there that a 8MM gearbox is too big for the gears let me know and I'll go a step down to a 7MM.

PLEASE NOTE: The gearbox in the link above does takes 8MM bearings

8mm>7mm>6mm

The modify is the best shell on the market in that price range! I run one and so do a few other guys from the store.

i have this gb

coby 8mm bearings do not affect gears in anway fitting wise LOL!!!

The measurement of the bearing is the outside diameter measurement where the bearing contacts the shell . . . shaft size/inner diameter remains constant across bearing/bushing dimensions.
