You're welcome.
Im no specialist for reanimation decks, but from my experience, some additional ramp is always useful because you usually don't want to play on curve.
I usually prefere
Fellwar Stone over Mindstone, but since you are playing mono, the card draw later on seems more valuable then access to colored mana.
Btw, depending on the amount of graveyard hate in your playgroup
Library of Leng could be interesting, since it also works for your own discard effects.
