Doug, if the Kyrol is bromated, use that. If it isn't, I'd go with the Mondako.
14%ish protein flours (Kyrol, Power Flour, KASL) tend to be a bit unforgiving when it comes to avoiding toughness/excessive chewiness. As you go a bit lower protein (Mondako), you can still get good oven spring will having to take fewer steps to avoid a tough crust.
