Nearly all the ones in my LBS are if anything thinner than Bikesters. They have a few winter ones, but IME thin is the default setting for most makes.
[Actually, I've just noticed you are in Leeds. My 'LBS' is in Barnsley, but last time
I was in SportShoes over in Bradford they had a rail of what you want. Amazing place - hidden away under a multistorey carpark but with a huge range of discounted kit. They specialise in last year's range of top brands at silly prices, which appeals very strongly to the Yorkshireman in me.
