Since you ask....
I expect I'll catch some flak for this,and know anyone can make any claim on a website, but using near perfect BS with adjustments for some of the "fab 18"and a generous amount of match play,free play and promo chips,I have had fairly good success since 2001.Counting the comps I've recieved,I am quite successful.
I used to use a slight positive progressive betting system,recently have used Oscars Grind(walking away from negative decks).
My last trip to Vegas I tried the OPP card counting method. It's quite easy to use,depending on the dealer.
My main problems with hi-lo was that-1)I found it mentally fatigueing after about two hours,2)could not both socialize and count, and 3)playing in AC at $15 tables,I didn't have the proper BR to be jumping my bets 5 or more times when the count was good.
Rather than making bi-weeky trips to AC,now I'm doing Vegas every eight weeks or so,so I'm planning on getting back into counting on the much better double deck games out there.
