Tossing 60s practice I hit one of these "Balancing Acts" which for me are far more rare than even a robin hood. You can aim for a previously thrown dart, afterall, but you cannot aim for a balancing act.
These are my 24 gram Mega-Thrusts from Bottelsen, with standard hammerhead points and a Dynastar back end. I am still waiting for my low profile conversion points so I can make these fixed point without them being ugly. I am infinitely patient. I guess.
