I have all 3 steels and do prefer the s90v for the stainless, however the extra cost of the sprint has kept me from purchasing chief model. The Rex 45 is a fantastic deal, upgraded steel, nice color g10 and not to hard to get. However Rex is not stainless so there is a trade off.
I would snatch one of the sprints asap, before they are gone.
Where is the rex version ?
