So... there are some wacky, wacky things that undead PCs can pull. In particular, I present to you Out of Hand. (Zombie 8). Did you ever way to have Flurry of Blows, without having to archetype to Monk? How about having it as a lvl 8 feat rather than a lvl 10? How about beign able to do all of that without gettign particularly near the enemy with your own fragile flesh? Well, here's your chance.
Out of Hand turns one of your limbs into a familiar, except that it has no familiar traits, and it can use your unarmed attacks (and your MAP) as actions... so you can spend one action giving it an order, and it'll make two attacks.
Seize is also pretty darned strong, especially if you like the idea of being able to grapple with a dex build. Feast is pretty savage if you have a party that can consistently arrange for restrained. If you've got a buddy to do the holding down, then having two detached arm attacks and a feast is a pretty strong turn, all in all.
Admittedly, you *do* have to accept being a zombie. Still, between grapple and grapple exploitation, "pack of zombies" starts looking kind of tempting as an adventuring group.

Predatory claws off the Vampire gives you the "free grapple attempt after hitting twice with claws" shtick whether you're using Vampire claws or some other. Does it work for Tiger Stance? It seems like it should. Admittedly,a free grapple attempt at max MAP isn't *that* great. More of a silliness than a real plan.
