Building a Bankroll

[HoldemPokerPlyr]

Alright so yes I'm going to admit, I went broke a couple of months ago. I've been depositing $20 here and there playing microstakes for a buit trying to build my bankroll up again. However, I'd almost double or so my bankroll and I end up crashing again. I would play mostly cash games. I consider myself a pretty good cash game player, except however the past few months I feel like I'm on a cold streak.

Anyways instead of depositing $20 bucks here and there and playing microstakes, I was wondering if I should deposit about $100 bucks or so and playing nothing but $5.50 9 Handed SNGs over at Full Tilt Poker. Would this build my bankroll up better than grinding it out playing cash games?
