Im using the OneUp Switch oval rings on SixC cranks. No complaints so far. Buy the spider and a 28T and 30T (or 32t?) ring and you will be covered for all the experimentation you need. I havent had to swap out a ring yet, but not having to take off the cranks and spider is a big bonus.
@op: I totally second that. Definitely go oval, and buy the switch with 28 and 30 in one go. Then you don't have any barriers to move back and forth between them if you want to experiment. And as you wrote you plan to ride a lot this season, your fitness will very likely improve enough that you can start with 28 and make the switch to 30 over time for good.
