Specifically the long 17″ grips, although they are new enough that I’ll guess there isn’t much practical experience with those yet.

At costs of $35 and $40 for some of those, it’s worth asking, I think.  Can it be done at all?

IIRC in earlier days this was done by injecting grip adhesive back under the grip from one end in order to.  Using a syringe, unless I’m mistaken.  It seems to me this could be done from both ends too, albeit at the possible disfiguring of the grip ends, or even the grip surfaces themselves.  But will it work?
