is it just me or do vertecs often seem to be leaning a little bit? would make a big difference to measured heights if so, and be a pretty serious bug in the design.
serious flaw for sure .. once you put them at their "max height", lowest part of the silver bar at the 10' marking, it's really "flimsy" and that's when you see the bend/tilt. If you have it at 9'6", it's ok. If you raise it ABOVE 10', using your own custom marking, where it's nearly about to come out of the base piece, it's super flimsy.
so yup, definitely spot on about a flawed design... it doesn't hold up well at mostly ~10' usage .. i think that's why you see lots of videos with people having it at 9'6" and having people still do impressive vert tests on them, it's much more solid/straight at this measurement.
peace!
