I think what he means is that you use it differently than a diminishing abrasive. The 105 is a great product if you need max cut and gets in, does the job in seconds and you're out. Where people have run into problems with it are the ones who worked it too long. I broke out my old Presta Ultra Cutting Creme light for kicks on the last 2 jobs..it still works great. I think you've been doing this long enough to realize that the products that people get so worked up about are only a small percentage of your success. The process and skill level are what's most important. If you're good, a lot of different products will do just fine. Having said that, technology does always move on and some new stuff comes along. The non-diminishing crowd really started with X3. I still have and use that a lot too. Just use a different method.
