Thanks. Halfords sell those hoods for £18, click and collect, but my levers aren't really worthy of brand new hoods.
Currently just tryng them out as brake levers with DT shifters. I'm going to try the campag 9 -Shimano 6 speed Shimergo setup when I can be bothered. Obviously, this means sorting out the housings and new cables. If it doesn't work out for me, I'll toss the levers back in the spares box again.
Swapped over MAFAC half-hood levers for prettier Shimano 1050 levers but they hurt my hands where the hideous MAFACs were fine. Probably a combination of the square-ish hood profile and where they're situated on the bars. Campag are better in both respects...
