Ok, here's the deal. I've got a flying hive tyrant and was thinking of taking 2 pairs of scything talons, though due to some thought I'm now taking old adversary abilitiy, which gives preferred enemy special rule - so the 2 pairs of talons are redundant.
I've managed to squeeze in a single pair of twin-linked devourers but I've kept the bonesword and lash whip. Looking at the sword and whip combo I'm struggling to find a huge amount of use for it. The tyrant doesn't allow armour saves as its a monstrous creature any way, and most things with multiple wounds tend to have a decent leadership any way i.e space marines, nobz and warbosses etc. The lash whip might make a few things go last, but the real damage comes from power fists thunder hammers and a-like, which strike last anyway.
So should I give the bonesword and whip combo a go, or just ditch it and get another pair of twin-linked devourers?
