thoughts on cbetting AK in position

I have been thinking a lot about how to play AK best in position when you raise preflop and get called and flop nothing. A few months ago I cbet it 100% figuring that I have the best hand a lot and have good equity to make TPTK vs smaller pairs and the slight possibility of someone folding an underpair or bottom pair type hand made it seem very very +ev but I have spoken with a highly regarded HSNLer who has suggested that I start checking in these types of spots for a few reasons:

a) yes, you may have the best hand but with my image, people will NEVER fold a better hand (e.g. a pair)
b) I can't really call a check-raise with no pair so this opens the door for me to put in a cbet and get blown off the best hand vs checkraise (semi)bluffs
c) your hand looks very weak when you check behind the flop so vs the right players on the right boards I can snap off turn/river bluff(s)

----

These are all valid points but when I think about sklansky's fundamental theory of poker which goes something like

if you have the best hand you should bet

with that said, if I expect my opponents are defending their blinds light and only make a pair 33% of the time on the flop and rarely have pocketpairs (since most people reraise those) doesn't betting 66% of the time (or more) make better sense than checking?
