Other than myself, and rongarm10, anyone else familar with Tony Leo who resides in LV. Tony teaches his own version of DI (both on DVD and in his home), but of more interest to myself, he teaches a betting method where he incorporates 7 $1 Hop bets progressive method into his play. You can find Tony on youtube, has 21 vids (under thegamingpro) of approximately 25 mins. each. The vid course is north of $500, maybe $600, the infrequent school which is held in his home not sure what that cost. If you are not into DI then this isn't for you, but if you are looking for a betting method using the Hop bets, you may find this of interest.
