Scobbie. It depends what you want out of the car. I recently had the pleasure of riding in Typos's 147 to compare suspension settings against my 156.
I run eibach sportlines (50mm) and autodelta sport comfort shocks
He runs Koni FSD's with eibach pro (30mm).
I've not tried full coilovers on an alfa but having had them fitted on a 205 GTI I can confirm they are very very hard.
Now non of these set ups I would say were uncomfortable or impossible to live with in day to day driving.
The 205 was awesome on road and track but became a little unsettled on very bumpy stuff making it a bit hairy sometimes. But the level of grip offered was superb and I recommend coilovers to anyone who wants great handling and has reasonably smooth roads in their area.
Typos's 147 again was superb in the bends and was a great handler although a little crashy on rough surfaces. Again if you are looking to do a lot of track work I would recommend these as well.
My 156's autodeltas are firm and grip fantasticly as well but that extra give just makes them more comfortable. Both me and typos agreed that our cars had these different aspects and that on a track his would be superior but on road mine edged ahead althought mine are very capable track shocks too. So Scobbie its up to you bud. I would way up what you really want to do and then fit accordingly. If you are only doing a little track work I can recomend the autodeltas. If you are planning to do quite a few events then go for the fsd's. If you plan to hammer it on a track as much as possible then coilovers would be a must. I think most people are in agreement though that for the lower options eibachs are the only choice

Hope that helps
