best ball cups??

[Dazzle]

Hi. Im after some new ball cups for my tm2 as I've a massive problem with them keep popping off!! I need long shank ones, and I quite like the rpm ones that come in a range of colours. However I made the most basic rookie mistake, and ordered a set before checking the measurements! Needless to say, they only fit 4.3mm studs and I need something that fits a 4.8mm stud.
Can anyone recommend me a company who produce a heavy duty version that preferably comes in a choice of colours please??
Thanks Darren
