Replying to What are the best new park boots?

I'm an ex-racer and i'm getting out of a race-fit (three sizes too small) pair of Nordica Dobermanns with a flex index of 150. I dont want completely floppy boots but i also want something thats gonna be more comfortable and warmer than my dobermanns. I'm 6'1, 150lbs (but i squat 300lbs so i'm not just a skinny shit)
I'm kinda new on the progressive/park scene so any help or suggestions would be much appreciated.
Thanks,
-Andrew
