Looking for a good 5.5mm (I) hook

[enmac]

I have two 5.5mm (I) hooks. One is plastic and has an annoying ridge along the centre line which always catches on the yarn. The other is metal, which is better, but the distance between the hook and the flat part where the thumb rests is unusually short.

Can anyone recommend a good brand specifically for this size? Also a good place online to order from, with overseas shipping?

Thanks
