No doubt it's the Center Force of Kurita that comes through the Sibuyen Sea through the San Bern, two long rows of capital ships encircled by many DD's. The Yamato's bring up the rear. As this group exits the San Bern it heads sort of SSE where it comes in slight contact with the US jeep carrier force. Soundd like you found them coming around Samar going fast. Lurker has them turning back on each other so they don't do a massive battle or the Yamato's would eat them alive, but I've seen a few DD's do battle. A good place to catch the group is in the San Bern, so narrow the group will have to come over you.
If you miss it, just remember it comes back the 26th. As you stated it's faster than your sub so if it gets ahead, you're not gonna catch it either way.
The other force is the Southern Force that comes through the Surigao Strait same night, but just two Kongo's and several CA's and DD's, but you'll see several US TF that easily deal with it. Nice surface battle and you can easily finish off many damaged ships.
Course also the northern carrier group, battle of Cape Equano as discussed in another thread.
Here is an old SS of the two lines. If you catch it in the Sibuyan Sea..think that's how it's spelled the 24th you can watch it get attacked in mass by planes, another good time to attack it and you have more room.
