Which Plan?

I haven't been following a plan, just swimming, biking and running when I can.  I train 6-7 days most weeks usually swimming 3X week, running 2-3X week and biking/spinning 2-3X week.

I am doing sprints this year but the one I started with was a super sprint and they are getting longer as the season progresses.  Depending on how the season goes I might consider an oly next year.  I've looked at the BT plans twice now and am overwhelmed and confused and not sure which to follow so I haven't graduated to the bronze level yet.  I don't mind paying I'm just not sure which to choose.

I have 5 kids and don't have tons of training time.  S, B&R are all new to me.  You can check my logs to see how much time I am putting in right now.  I do have a bot more time to devote but don't necessarily have the endurance yet.

Any suggestions would be appreciated.
