Paint roller sleeves - which are best?

[spada01]

I used to use Screwfix cheap and cheerful ones for emulsion onto walls, but was never massively impressed with the result.

A question for the professional decorators - what do you guys use?

A Pro told me that he uses lambswool, but some others prefer microfibre.
TBH if you want a very smooth finish and are a beginner I would try a Harris paint pad. That's what I did. It looks immaculate. The problem with rollers if you are a beginner is judging how much load is on the sleeve, a bit of spattler, can't get anyway near corrers and orange peel.
