Personally i like the Slayers a lot. And if you don't like the old or current Slayers, there is the Berzerker Box from AoW which is an awesome Deal. I believe they could also mix really well with the GW Slayers.
I'm gonna get like ~20 Drakes, ~30 Ironbreakers with Shields which i will use as Clan Warriors, some ~30 Longbeards with Shields which will be my Ironbreakers
alongside the metal Longbeards/Hammerers/Slayers. Also gonna use Bugmans guys as X-Bow guys with 2handers. A couple of Bombers too i think. I'll also try to get enough of those Shields that the new Ironbreakers have, so that i can equip my whole army with those!!
I'm really looking forward to get back to my Dwarfs!
