Heads up SNG's, bankroll question

[grouchie]

Recently i've begun playing more 6-max cash games and I have started playing some of the $5 heads up SNG's on stars.
I'd like to leave money in my Stars account for that purpose only and see if I can build a bankroll and continue to the higher games.

Only question is, with something that will have as much variance as heads up, what type of bankroll would one need?
is 50 buy-ins adequate?

anyone with experience i'm interested in hearing your advice.

The variance for HU is very low. If you wanna know how low, search HU and my name in the search function, and you should be able to find a thread from a week or two ago in which I gave the formula.

50 buy-ins is way more than adequate. I think ten or fifteen is fine; some say more like 20 or 30.

Also, it doesn't matter how many buy-ins you have on a specific site, it just matters what your actual br is.
