Can you deliver a touch special ability via natural weapon / weapon / unarmed strike

[Ximen Bao]

I know that you can Hold the Charge and deliver a touch spell via a natural weapon/weapon/unarmed strike attack.

But lets say that I have SU abilities that read "Make a melee touch attack. If you hit, X happens"

Can I choose a natural weapon/weapon/unarmed strike to deliver that ability?

Reason being, I might want to use something with reach, or an enhancement bonus or whatever. Or am I limited in those cases to getting up close and poking with a finger (and not using unarmed strike skills)?

Short of the conductive property or something of the sort, the touch attack isn't the same as a held charge. You'd be limited to finger poking.

There are also various feats in UC to cover that... hex strike, school strike, sorcerous strike, depending on where you get the SU ability from.

A +1 Conductive Bodywraps of Mighty Strikes is also a good choice, leaving your AoMF spot open for an unarmed focused character.

I had misremembered what conductive was. I knew there was something like that. Thanks!
