Covering Bets question

Wong's site says that if your not betting above $100 there is no need for cover betting. Being that I've yet to count at a Vegas casino, I thought I'd throw it out there.

Can anyone offer their opinion or experience on not doing much or anything to cover $10-$80 spreads or $5-$75 type amounts? Are there known casinos that are inattentive/harsh to low dollar counters?

Thanks

I haven't had any problems in Ontario or the Dominican Republic with wide spreads under $100. Although, there was that one time that a pit boss commented to me that "I was doing very well" as he was making a note on the loyalty point tracker card. I took a walk after that just in case...

I have read stories about people being backed off at the low levels, so I always try to have an act going for me regardless of the level I play. I wouldn't count brazenly and expect to get away with it every time
