powerflex40 vs powerflex70

[swtjhny]

I am designing a system which utilizes several different pumps. I have always used powerflex 4 and 40's for smaller motors in the past and powerflex 70's for larger applications. Thru research I have found allen-bradley makes big HP (20hp) PF 40's, I would rather use the 40's due to the fact they are more user friendly and the 70's have way more options than i need. Has anyone ever used the larger PF 40's? If so what are your thoughts?

I have used just about all the PF40's, hp sizes and have not had any problems with any of them. We have ton's of them in our plant.
