Summer/Winter Wheels

Show me a reliable, full carbon clincher for anywhere near the price of PX tubs and I'll agree with you.

Albeit they're 2nd hand and a lot of people don't consider them reliable: http://www.ebay.co.uk/itm/221004544085?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2648#ht_500wt_1287

IMO summer/winter is all about the bike not the wheels :)

That's not good news for a skinflint.

You could swap your Competitions to Sprinter Gatorskins for winter, however the grinding paste that winter throws at your bike would be quite rude to the braking surface I think.

I fear you speak sense, I imagine it's not a such a big deal if you've got carbon wheels and know what they're be like in the wet.
Just the price makes you think twice.
