It is too bad this thread has gotten off track, and I have participated in that.
As I mentioned earlier, I know diddly about skiing.
I am glad you brought up the Mizuno Shoes. I know a little bit about them. If you are familiar with my posts, you would know I do a lot of hiking in XC flats. And the Wave Universe series were designed just for that, running cross country races, although they are now marketing the 4's as minimalist shoe to capitalize on the current minimalist craze. I strapped on my first pair of racing flats in 1967, so they are not new to me. XC flats are for racing in XC meets, generally 5K in high school, and 8K in college unless you run in the NCAA Regional or National finals. XC courses tend to be gentle rolling terrain. You would also know that I have hiked in several brands of XC flats the past few years, mostly Asics and Sacouny. You would also know that I do not advocate them as best or even better shoe than other options. They are just my preference and not a viable option for most people.
Now, if someone wrote an article about general use trail running shoes that would interest a broad cross section of BPL members, I would not post that you forgot XC flats or even that they are better. XC flats probably fit the need for less than 1% of the BPL membership. An article about minimal trail running shoes on BPL would probably not include XC flats; they are not designed for trail running. I might mention them as a lighter option and leave it at that. If people want more information on my experiences, I am more than willing to share them. I also have shared the negatives about cross country flats... they don't last long (very high cost per mile vs other shoes), traction is not great, no rock plate, not good in cactus country, you need to be agile, you should be carrying a very light pack, etc.
I probably have recommended Salomon Comp 3Ds more than any other shoe, because they fit me well, and would be a good all around choice for most people here if it fits them properly. I have 3 pair, each for a specific need, but probably do more hiking in flats that don't last. That is what works for me, and will not work for most people on this site.
And this is the point. Seems Dave wrote an article that would appeal to a good cross section of BPL members, and you keep pushing the benefits of a specialized and more expensive option. As I said earlier, a simple post of "you may want to also consider this, because of XYZ instead of beating it to death.
And yes I mention cost, because it is important to a lot of BPL members. I am fortunate because I have been working for over 40 years and my kids are grown and gone. So I can afford to spend more discretionary income on my hobby. Others here cannot, or have additional responsibilities that I do not have. I am very sensitive to cost for that reason.
BPL is about sharing information, knowledge, and experiences. Usually there is no right way. What works for one person many not work for the majority.
To be honest, the best thing for you to do is to let this thread run its course and let those interested in Dave's system discuss it. There does seem to be an interest by some in Rando racing. Why not start a thread on that subject, where those who are interested in it would get some real benefit. This way everyone wins.
