Brake levers?

Cross tops work great, are super light and pull well. Those Diacomp dual pull levers are awesome. No idea where to get them in the UK, but the sub part is just so you can brake with both hands, but obviously the smaller side will have less braking power.

+1 only the stumpy one will have less power, the normal lever will act a normal cross top lever.

I noticed Charlie the bike monger from that there ebay has started to stock some Gran Compe bits, maybe he will get these in. He has the Gran Compe Track cranks which look positively diseased.
