At lower lvls I'd go with protector but later on you'll need armor or a very good set of protector. You can try protector/armor mixture, however if you mix them you won't get the protector set bonus which is 10% more speed and 10% less mp consumption.
Well, thats my opinion, never had an (hybrid) int spear nuker. They seem too vulnerable for me:P But with a good set and weapon they pwnz.
EDIT: Oh, welcome on SRF
