At this point, I think G/P and G/F are safe bets for the podium, though I don't think the order is as set in stone as some others seem to think.
Based on scores throughout the season so far, the other podium spot, to me, is wide open between F/G, FB/S and C/B, as their combined totals from their 2 events (414.74, 412.34, 411.93) are all close together, and are also quite a bit higher than H/B's combined total score of 404.53.
