I've trained using "strip sets" in the past. But It seems that I used them a bit differently than you are.
On the final set of each movement I would have my training partner strip enough weight off so that I could get another three to four reps.
I only did it on the final set as I did not want to take away from my strength on the other sets of the movement.
For example if I was doing Barbell Rows and working: 135-12 185-10 200-8 225-6 225-5 or 6 (strip 50lbs. or so) 175-4.
I felt that if I did each of the preceeding sets with a strip set at the end I would not have been able to go as high as 225 on the final set. And I think that weight progression is far more important than anything else. Afterall it is called "progressive resistance" exercise.
Make any sense?
