Underplaying my hands

[Watkins]

I've been made aware through my recent session review that I'm probably underplaying some of my TP hands. I'd be interested to know the standard line in the following situation:

UTG+1 is loose and running at 30/3
MP3 is TAG and running at 15/11/2 so this could well be an iso-raise

Is this a fairly straightfoward preflop raise? What about from CO/BTN?
