thanks mike for keeping this going for so long ............ sure do appreciate it ! i found the pentagon level harder than the hexagon, which seems weird. however, you need to sign-up to get access. monument is successful for the same reason. all products are available either ready to finish or with a factory applied finish. in principle the 690 rally remains the same. it’s hard not to break a sweat when you’re in this key position, as you’re engaging your core while holding your body-weight up in a strong, stable position.
