When you say you believe in checklists, I presume you mean written ones.
Personally I agree with the military way of doing things, ie. memorising all the checks. By working your way methodically along the panel, checking as you go, the aircraft becomes its own check list. If it's there, check it; if it's not, don't. This means that pre start-up checks take a fraction of the time that they would have if I'd used a written list. Best of all, you can't accidentally miss things off the list, because the aircraft itself is prompting you.
So yes, I always do a full pre start-up check. Despite what you say, I hope that this answer will help you.
