I have a 436HP on the way and my plan is to purchase ARC 536 to go with the Sentinal software. My question is will I find the ease of use with it as compared to what I have already been doing with FreeScan and my 996XT. I did not find it to be very difficult to pull directly what I wanted from the RR database and create my own scan lists in the past. Can someone let me know how similar the experience will be? I do have a premium subscription to RR as well.
