I have never read of anyone who has played this profile, i know that we need smoke, but i think that a second Kriigel with this is much better than the phero-booster or another smoke. In a tri-core he can launch grenades on bs 12 speculative! (12+3 for core+ 3 for range - 6 for spec). I think this its amazing and very useful.
if you play a lot of zone control missions where folks plunk dudes on rooftops (who aren't in impersonation state - camo is easily dealt with using one of those four chaksas you're taking right?) then this guy can be worth it. However I find that when I'm facing soldiers hiding prone on rooftops they're usually impersonators & thus safe from the grenades unless you climb up to dig them out the hard way. I make use of spec firing grenades in Morats and with EM in JSA, the Igao with stun grenades can be quite beneficial if you want to nuke a link team before eating them in close combat (or are playing Hunting Party...), but I think that a single Kriigel with smoke is more often all that you need - he's your maneuverability and defense tool. They're pretty expensive to double up for the limited utility - again, unless you find a lot of dudes prone on roofs.
I've done double Kriigel but I usually end up doubling the Smoke LGL guy. One in group 1 for linking with a Draal and Tricore Taagma, and one for group 2 with two Reex to produce orders for a specialist or to be able to create some space to manuever without spending precious group 1 orders.
