I'd guess that SKS Chromoplastic 700/45 would be the default choice.
Having just fitted 2 sets to the winter bikes I'd say that they are superb.... but the person who wrote the fitting instructions should be dragged outside and slowly beaten to death with a D-lock.
If you're not 100% mechanically confident, or don't possess an extensive vocabulary of interesting and varied swear words then it may be worth getting them fitted at the LBS.
