imp life tap vs. imp impFollow

I'm stuck between a 41/9/11 build and a 43/7/11. The only difference is that in the first I have Imp Imp and 1 HS point. The second has Imp life tap and 2 point HS. I'm a pve raider with my imp always out for dark pact. I don't really do pvp besides the ocassional run in with an ally in world pvp. I just can't decide which would be more beneficial for pve and raiding. sorry for no links, this is my first post and i'm still tryin to figure things out. thanks!

Idk - LT will require you to either drain-life it back (dps gimp) or use up your healer's mana. BP+imp imp gives you "safe" mana. *shrugs*

As a raider you can have a max of 5 points in demo or 21+. Stam talent is not for raiding!!! (some encounters migt need other things ofc)

Imp LT is more important than imp imp imo. Even tho you have dark pact, you are still gonna use LT several times when fighting a boss.
The thing about you needing to drain to get it back is just lame. When i LT in raids im usually healed before i get done with draining. Tbh i doubt the guy that said it has ever raidet past kara.
If i where you i would go with something like 42/2/17. destructive reach is important good. Also you dont need fel concentration when raiding so you should be able to get all the points you need in the affliction tree with 42 points.

As for the imp imp ask your warlock CL. Only 2 of the active raiding locks need imp imp or as loke says imp BP.

If DT means Demonic tactics then notice i have said 5 points as a max, OR 21 or more. Which means 9 or 7 points isnt ok.

Im actually using 0/40/21 atm since im tanking leo. But keeping succy alive is pretty hard so in most fights i end up sacrificing her.
