replacement BAR ends ??

[Joe]

Hello,

I was thinking of getting some after-market bar ends, as I have a bit of buzz coming through the handlebars....

But I was warned by my service guy that these OEM ones were in fact "heavy" and anything I was likely to find would be "lighter" thereby NOT solving the problem.

Has anyone swapped theirs out from the OEM set ??
What did you get & from where ??
Are they heavier than OEM ?? 
Did it work to reduce the buzz at you hands ??

Thanks !!
Joe
