golf 2 gti rear axle bushes

[sidgolf]

the time has come to change these on my 16v.
for me the choice is between using o.e. volkswagen bushes,or going over to easier-to-fit polyurethane ones(super-flex etc.).
2nd choice would be easier and cheaper but ive heard stories that fitting these no doubt longer-lasting alternatives to originals can upset the handling of the car,making it quite'twitchy'.
im minded to go with the poly-bushes,so has anyone had any bad experiences with them on these cars?

everything else has already been changed to polybushes,-20mm eibach springs,g60 top mounts etc.etc.. guess i'll just toss a coin...
thanks for replies anyway.
