Like everything else, it depends. (K,T) ain't much of a hand right out of the #1 hole, lots of ROI there. If the table looks weak/passive, lots of foldy nits, then it's worth a steal.
It's also worth the occasional steal attempt OOP (and I'll raise a lot of even weaker hands for this) to keep your opponents guessing as you don't want to be seen raising out of the #1 hole with just JJ+ and AQs+. If that's what they think you have, you'll get called every time the flop comes down without an ace, king, or queen on board. If it comes (T, x, y) you want them to know there's always the possibility you might have something like (K,T-o) to give your c-bets added credibility.
Just don't overdo it: it's a ROI hand that looks better than it really is, so fold most of the time. Never limp out of the #1 hole.
