grips: cork or leather?

[elk]

I have the prettiest cork grips for my new Albatross bar...but I can not seem to make them stick...they're just a little bigger than the bar..grrr

Rivendell suggested the very adhesive I used (3m 77).. I might have to try Gorilla Glue which expands.... or

Meantime, I have these leather grips that I have yanked and twisted and stuck sharp things into, sprayed with alcohol about 5 times on off on off on off and they still long to serve...

i'm about ready to let them....

Broke out the Gorilla Glue (per some research here) and it might just do the trick...scary !!
