It's pretty simple: Torrent in all circumstances, except where you cast enough HW to make the Und proc meaningful. UL is worse in all circumstances, except where mana is prohibitive and you use a lot of CH like for Ursoc.
The break point for Und procs for Und vs Torrent is a good question. You always cast RT on CD in most circumstances, so that's a static benefit. At what point is the SP gain there (I believe it's 100 SP per 6s) better than what Und would provide?
Und is a 50% bonus every third HW or HS cast. An Und HW is going to be a 237.5 SP gain per, roughly, 6 seconds, since that's what we use for a HW RT cycle. The gain for a HS is going to be 361 per 6s, assuming HS is TW buffed.
So, that's 3 HWs in about 14 seconds before Torrent equals Undulation? If you use HS, that's 1 Und per roughly 21 seconds. Using rough numbers because this is all super approximate in practice.
The numbers are deceptive, keep in mind. 40-60% of your active time is going to be spent casting something other than CH, HW, or HS. So every minute, you have more or less 30 seconds to cast HW/HS for Undulation procs. You'll need to spend 9-15 seconds of that casting HW or HS for Und > Torrent. So 15-25% of your active time. Might be off on something since I haven't double checked.
