I use Chris Ferguson's method of opening with uniform bets based on position. Early position = 2xBB. Middle position = 3xBB. Late position = 4xBB. Using this masking technique, I would open for the minimum raise UTG all the time. It's common wisdom that you should never, ever enter a pot with a flat call of the BB. However, I think a minimum raise is acceptable if you're using the Ferguson strategy, but a lot of players disagree and equate minimum raising with flat calling. To each his own, but my way has its method to the madness.
If I'm holding a premium hand, which I usually am if I'm entering the pot UTG at all, I can always re-raise that by-the-book raiser to my left. But if I want to mix it up a bit by playing a more marginal hand and someone raises, I can easily muck it without costing myself a lot of chips. If someone is paying attention to my "betting patterns", they'll soon figure out that I could be holding AA or 78 suited. They'll never know until I rain chips down on them. And if I do, they'd better have a monster.
By the way, if you're a new player, it's worth noting that Sklansky's Group I is widely recognized as the only cards you'll want to regularly play UTG: AA, KK, QQ, and AK suited. But you're also going to open with those for a big bet that only a donkey or someone with an equally big hand would call. Unless you're using the strategy I explained above.
