A good option for moderate moisture, but we often use the 0/-10 with 1mm&2mm linear tools instead of this. We'll continue to test this one and will revise our recommendations if it shows-up as a better option.
Red Creek hand structure tools are highly functional and easy to use. You need to push on them pretty hard to make a good impression, but the good news is that it's almost impossible to ruin a ski by pushing too hard! These tools have the reputation among the European pro marathon teams of providing good benefit for the duration of a long race, while more aggressive tractor-box tools have been connected with slowing skis due to pollution. We have been utilizing these simple rolling structure more and more over time, and have been very pleased with their performance.
