bung for carbon forks - here's an idea: glue one in?

I'm about to fit a new set of EX90X carbon forks and have been thinking about which internal bung to use.

Has anyone heard anything about glueing one in, rather than using a compression fit?

My thinking is that the forks, once cut, won't be transferred to another bike so flexibility is not a factor, and a glued bung would be lighter, potentially, as it wouldn't need the compression bit.

[as you might gather, I'm on a bit of a weight weenie thing at the moment]

    Why not just remove the bung and headset cap and bolt completely to save weigh once the stem has been fitted?

    Easton used to provide a snap on plastic top cap that simply clipped into the stem, back when they used to provide the awful bear-trap external headset compression unit with the EC90 SLX. I take it this cap doesn't come with the newer Easton carbon forks?

    I'll dig around in my spares box, just in case it's still lurking around, even though I got rid of the forks...

    And I think certain 3T Funda forks have some kind of glue in nonsense for what it's worth.

    I guess you're not planning on removing the stem or servicing the headset then? The bung also prevents compression damage to a carbon fork steerer - they're not strong enough without them unless you have a glued-in sleeve like the 3T.

    @ Maddog2

    OK I found the Easton "plug in" top cap in my spares box. It just plugs into the steerer tube. PM me if you want it or want more details. It weighs a whole 5 grams.

    That can't be true for all forks since Easton didn't use to provide any kind of internal bung, the bear-trap provided was external and fitted in place of a headset spacer. (That's why I've got the above). You'd have to be more careful with torques though.
