Alignment settings and where??

[goon1001]

After chatting to people today at the TVRCC meet, I feel i should get the alignment check on my nitrons as they have been on a year now and it feels a bit skittish sometimes. Where can I go in the Herts/Beds region, thinking either Sebring, Northampton Motorsport, Or poss Top Cats. Any recommendations welcome and should they know all the settings or would I need to take them with me? Is corner weighting worth the money too?

thanks in advance
