If you are going for some specific build you know you will use, you can compare costs of individual mods and polarize for the most expensive ones.

If you want optimal polarization for multiple builds, polarize one or two unused scratch slots for bars. First two powers are really cheap point wise, so you can put them in one of the unpolarized slot later if you change your mind. If you are using all slots for powers, leave all four for a time being and polarize some of the blank ones to bars. Great deal of useful mods is bar type so it will always get handy. Continuity, Focus and Rage are V mods and builds with more than one of them are scarce, but if you plan on using them, one V slot might be of some use. From useful Ds there is Vitality, Redirection, Narrow Minded and Quick Thinking, all pretty expensive mods but NM and QT are usually used in specialised builds, so those two default Ds should be enough for a while.
