Canadian bettor here out of Wpg who has decrease his betting a lot through HPI and have moved back to Betfair. I was only using HPI for the win pools of Hst and WO. Playing American tracks out of HPI for me is just dumb, and an unbeatable takeout IMO. The only thing I can say is that my Asd rewards is through HPI, and Ive got some nice returns on that front.
If you REALLY want a good story about HPI giving back.....
