Anybody play slots on their Casino bonuses?

[TwoNiner]

I haven't really tried to bonus whore from casinos since the days of auto play blackjack money. But with some of the bonuses I was thinking about just dropping the 50-100 in and playing the slots trying to hit a big pay day on a lot of the sites. Do any of you guys try this? I see Audited records for slots on the whole for sites, but are there certain slots that are way worse than others ( IE probably the more popular ones). Anyways, the casino bonus game seems like a fun break from poker, but at the max deposit levels I just can't see trying to grind out blackjack without autoplay and was looking for a fun way to gamble. I figure most of the time I'll lose my small deposit but I'll give myself a chance at a decent payday with the strong backing of the deposit bonus. Any EV knowledge or experience at this in particular would be appreciated.
