Your fitting is rated at, between 75 - 85 Watts, so the 65 Watt
starter is only faster because you've over loading it.

Sounds like that to me too.
Surely one can fit higher rated starters to lower rated lamps?
Could be there's a problem with the 125W rated starter or lamp.

I've just had a quick look on the web and see you can buy a starter
rated between 4 to 80w which is probably the one I need.

If you are concerned about flickering/delay then Maplin do an electronic
one which will start faster, without flickering and has a rating span of
30-125W. Costs about a fiver.
