Texas510:Scorpians and grizzlies easily beat ODSTs, combine it with the carpet bomb or cryo and it'll be fine. Don't build flamethrowers, they're short range, lose to everthing except some infantry, and they're easy to counter.
No autually scorpions are decent, but flamethrowers with oxide and adreanaline completly rape Odsts.
The first time I played as cutter I teched to ODST and the other cutter I was playing with knew I was doing so and upgraded flamethrowers and made them.
Believe me this is hard to counter if you lock your base so he doesn't know that your building flamethrowers. He'll think your teching to ODST aswell. You also want to produce units that are good at destroying bases to. Yes indeed they are easy to counter, but you don't need to max your army cap with flamethrowers. Instead throw in some wolverines and maybe some cobras.
