I stopped using DH psychic rules years ago,
What do you use instead? And how have you merged these rules with DH and the Psykers advance schemes?
At this point, I'm using a mish-mash of psychic powers from both Black Crusade and Only War. I don't have an exact list of which ones I allow and which I don't - I just go over whatever the player wants and make calls. I keep telling myself I should sit down and merge the power trees from both games into a "psykers' handbook", maybe take some time to convert the cooler powers from other systems as well.
As for accomodating the Psyker's advance tables, you could say I didn't - psyker-related Talents that don't exist in either BC or OW don't exist in my DH games, Psy Rating is available for purchase in accordance with the advancement tables, except it works like in BC/OW (i.e. it doesn't give psychic powers at all, just contributes to the focus power roll and meeting power/Talent prerequisites). Powers are available for purchase as long as the psyker meets the prerequisites that each power conveniently has, and they cost their stated price in exp - generally, this means psykers have a lot less powers than DH assumes, and most of the really good stuff is locked behind higher ranks, but that's okay with me and my group.
