My Omega shoots both the SST/SW and the TMZ well with 120 gr of BH209. But the edge went to the SW/SST at long range. I went with the bonded SW/SST. I need to do more testing with the TMZ to see if I can get them shooting well at 300 yards though. I would not feel handicapped using either. As of now, my gun will have 300 gr bonded SW in it this October.
