Pedders rear diff mount insert - worth the effort?

[Lincsls1]

As part of my Monaro rejuvenation and preservation plan, I'll be fitting a new rear diff mount soon.
I'm considering fitting it with one of Pedders insert bushes at the same time, was just after some opinions on their effectiveness, if its negligible, I'll not bother.
Some have said it makes gear changes a little smoother and even stops the gear stick bobbing around as much?
Thoughts please before I spend even more on the money pit
Cheers...

Thanks for the advice guys.
I've already had a new OEM g/box mount. I've got a new OEM diff mount on the way and I'll shove an insert in it before fitting to the diff.
One day I'll replace the engine mounts with new OEM or Pedders.
Must say, I've recently fitted what was the Monkfish RRP and QuickRack, this has sharpened up the car very nicely.

^^^ Spent hours recently recently watching videos of this job and looking at the different brand of bushes.
The entire front end is now new, I've got rear springs and shocks on the way along with a new diff mount and insert.
Seems I've got the modding bug again, but I think I need to have a break once I've fitted the above.
Let the finances recover a little! I've even been considering an aftermarket steering wheel!
