Looked in the old postings and couldn't find an answer to this one so forgive me if I missed it
Is it ok to replace the rear pair alone?
I'm rapidly chewing through mine (3000 miles since 1st Feb)
It currently has Pirelli P7000 all round and I was thinking of giving CONTI SPORT-CONTACT a go?
Any thoughts?

Thanks for that. Just seen an old Autocar Jan 29/03 and they reckon Pirelli P-Zero Rosso are the dogs' gonads.. Anyone used them?

Getting a pair of Conti 2's put on the back tomorrow for £350 from a local dealer. (only 3 miles)
The front's have just too much fat left to change yet
Been out this afternoon giving the P7000's their last rites
Now have to go and wash the 3,000,000 bugs off the front
