Anyone here used slick tyres before?

Question

I want to replace my off road tyres on my mountain bike with the road tyres on the link below but I need to know if in wet conditions are slick tyres likely to lose grip more than off road ones when cornering fast? What do u think of these tyres? http://cgi.ebay.co.uk/Continental-Sport-Contact-MTB-Road-Tyres-Tubes-26-x-1-3_W0QQitemZ160253288703QQihZ006QQcategoryZ27954QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
