Nick - after the jerk, if you are then lowering the weight to your front delts, then thighs, then floor, then I'd guess that 5x5 will be too much towards the last few sets.
but if you are dropping it from above your head, then it might not be as bad.
RIP suggests Powercleans be done as 5 sets of 3 reps... I found this pretty difficult towards the end as I was lowering the weight back to start position, while I was doing his novice program.. but it was after squats and press.
