XTR + SP41 in 10 metres was a great purchase – the XTR fittings can then be swapped over when recabling so all you need for many years is the odd new inner (at whatever expense you like i.e. std, high Qual or coated) – cut the same lengths of SP41 and then just pull the rubber gromnits/cable ends over and hey presto :)
If its full length your after just get SP41 and a good qual inner – pref coated :)
