Ok - done a little more research and decided I'll use a Hydor L30 because I want a powerful, quiet pump and the L30 seems the best for that (generally more powerful seems to be noisier - I based this upon the pump review on the main site).
I think I'll then go with the two radiators (BIX - one on each line) as long as I have space and enough money. Any more comments on this? Please?
