I bought the 5 speed pink box with lightweight fly wheel from Aztec.
I had a bit of trouble pulling away at first, not sure if it was judder or just dodgy clutch control haha. But it was quite bad for the first hundred miles, but got a lot better.
Hardly does it any more, unless I go on quite a long journey and get stuck in a traffic jam, then it makes me look like I can't pull away smooth.
I'm no expert on clutches either so bearings may be an issue with yours, but the garage I got mine fitted at was Scooby world and they took it out to test it was all ok.
The only thing I get with mine all the time is a rattling sound when I'm just rolling in gear with no pedals depressed. Scooby world said it can happen with a lightweight flywheel.
