I think only storm bolters can be upgraded with psycannon bolts or sdoes the psycannon bolts cost include the pts for the storm bolter.

I don't really see why people in the DH forum complain of anti tank when you have this melta bomb strike what other army has it? (discounting Smurf hyperios's)
first, if you really read the entry for psycannon bolts as a vehicle upgrade, it specifically states what weapons can take it.
second, we be-atch because the orbital strike (all of them) are so unreliable to actually hit your target that you want. so the unpredictability of it is a waste
and third, for DUDEMAESTRO, drop WOTE, as it is entirely pointless. consider how many squads out there will fail their LD test that is worth sending at the termies. examples of what would assault them anyways: banshee's, hawks, avatar's, wraithlords, incubi, marine hq, anything with access to power weapons...primarily have a high enough LD that they will pass
