Of course this helps. Your response is well within the spectrum of what I was hoping to learn. That is, good manufacturer's to work with, preferred frames, rims, etc. I feel no reason to pursue the 'boost' technology and have no concerns regarding the standard 27.5 MTB.

As an example only, I can refer you to the ICAN P9 frame. My son is interested in more travel than 150 mm and this is why I added 'DH' to my thread title. It is also clear ICAN has made their share of errors so I am hoping this thread can provide me with some additional companies to do business with when the time comes.

My son and I are most likely to need larger frames but he can also use a medium depending on the sizing of the manufacturer. My wife and are are interested in the 140-150 mm travel frames but she needs small or XS.

If we can get current or nearly current geometry that is great but I think we'll do fine with geometry dating back as far 2014. I really do not know where do draw a line regarding this issue.

Please let me know of your suggestions or experience with a particular frame in the enduro, super enduro, and DH categories. I am interested in 27.5 or 27.5+ frames.
