jillians different dvd's

lin7604

i have 30 ds and love it. I am on my 2nd round of it. When i am done it i do want to try something different. I have heard of ripped in 30 and 6 weeks, no more trouble zones, etc but not sure which one would be good for me. what are the area target zones? how much harder re they from 30ds? level 3 is still a bit tough for me on 30ds, so i don't think i want something harder then that yet.... any suggestions out there would be great. thx
