Modern films are pretty durable. They don't need hardeners and don't usually give any problems with reticulation. To demonstrate reticulation to a class once I had to use really hot water and then ice cubes to have any effect. The charts for Kodak XTol go to 82 degrees. I believe that is the highest they give, but you can look at the chart and the increase is mathematical so it's pretty easy to figure out. I used to go to the trouble of putting ice cubes in my Jobo but no more - it's not necessary! Take a few experimental rolls and try it.
