i guess “high-schwall” maybe would be more appropriate?
to that end, the wall and interior (recessed or otherwise), typically fashioned in schmoove grooves, a straight vertical wall, etc have their goods and bads.
a flush straight vertical wall can lead to higher friction, lower stability, etc. schmoove grooves can help with both of these, but…
the schwall design, in addition to being stable in itself, is also very ‘correctable’ in play, and forgiving… this is true of the Project Y and PV44. the apex of the schwall provides for great correction and control - imo, and regardless of your skill level.
the gap area to a wooly markmont or ywet are good examples of earlier designs.
for a more contemporary comparison, a Project Y and a Diptych. the Diptych maintains the standard schmoove groove, whereas the Project Y maintains the large schwall. I’d say that not only is the Project Y, despite it size, more stable, playable and forgiving than the Diptych in part because of that design… and significantly more accessible…
but, i digress lol… “high schwall”
@vegabomb tgis wasn’t for you btw, more of a general explanation
