I'm going to be participating in a 1k tournament next month and
IG is on my list as well
Mine consisted of 2 units of 2x wyverns, Pask+executioner (tank commander) and two platoons on foot. The platoons start out bubble wrapping if I'm up against a drop pod list otherwise I've got foot sloggers running around trying to get to objectives. Wyverns are just awesome though - never leave home without them.
My other list I'm looking at is drop podding
SW. I was able to get 4 pods+5man+1leaderdude+2 meltas and a fast attack pod at 1k. That's what lead me to be ready to bubble wrap because 3 well placed melta squads would wreck my
IG list. Not that a 5+ save would be a huge help it's better than nothing.
