HAG style not fit for microNL? + VARIANCE!

[Life Tilt]

So I was a pretty standard TAG, moved to LAG, and expierienced some bad variance, went back to TAG, more variance, and now plan on experimenting with the HAG style. Is this -EV to do at the low stakes?

P.S. How long can a downswing last? I've been running really bad for a year, but am still up around 400-600, half of which came from donkaments. I have friends who are very good online players, watch me play and tell me I'm just running bad and it'll go away after a while. Maybe I haven't played enough hands? Only played about 20-25K the past year, that might be it?
edit: micro NL is NL10 and NL25 to me
