It's a small sample size, but I actually have a pretty decent track record in the 90-man KOs on FT, at least better than the smaller field SnGs at the same buy-in. The competition tends to be both softer and overly quick to shove/call to score bounties. If you'll more or less forget about scoring bounties and concentrate on good play, while letting these bozos knock each other out, you'll be better positioned to cash or take 'em down. You will definitely get called down lighter, especially early on, but as long as you adjust you can exploit that.
For instance, the 45-player $26 SnGs are stocked with regs and can be very tough. The $26 90-player Turbo KOs are way easier. For some reason, recreational players who wouldn't drop $26 on a regular SnG are sucked in by the bounty format, and a lot of regs are turned off by the turbo format so they'll avoid them. The fact that it's a turbo is counteracted somewhat by the fact that it's a deep stack tourney. So you can afford to be patient early on while all the splashing is happening, then when you do have a big hand it's pretty easy to double up and score a few bounties along the way. But to me the bounties are just gravy, I don't really consider them much at all when it comes to strategy. Also, the bigger field of the 90-player KOs means bigger payouts, from a softer field. These guys chasing a few bucks in bounties by constantly putting themselves at risk when they could almost coast into a triple digit cash are nuts.
