Balance on one arm, on two arms, Yoga practitioners do not reach the level to which Equilbrists are striving for.
Never seen a Yogi do a correct two arm handstand that will lead to above 5 min holds, or even greater achievements like 20-30 min on two arms in the same place, or the best I have heard 1:20 hour two arm handstand. (by an ex-chinese acrobat who teaches nowdays in the SF circus school)
The only thing worse than a Yoga handstand is a capoeira handstand, and I am a capoeirista, but I have to admit it. No way will you achieve such high levels as described above with such a bad postural alignment. My 2 cents.
