I can't tell you which one you should choose, but perhaps this info would help:
- Reactor 6000: this skate is essentially the One100 with some new colors and a few new features.
- Pro: Much stiffer skate than Reactor, but the fit will be similar. If you don't want a skate this stiff then go with the Elite model.
Cowlings on both are the same, though the Reactor has a 4mm runner and the Pro has a 3mm runner. Hope that helps. Give our customer service line a call if you want to talk more about the skates.
