Poly bushes vs OEM?

[Clammy]

I'm just about to replace the front lower wishbone and anti roll bar bushes on my 328 and I'm wondering whether or not to go the Powerflex route.

I'm not exactly keen on more road noise/vibration so I'm thinking of going OEM but then I'm keeping the car for another 18 months at the least so I don't want to have to swap them again in that period.

Any thoughts would be appreciated.
