What you are saying does not make sense. He has a 6" spring - if it does not bind with helper springs, it will not bind without helper springs - once the car is on the ground, the helper springs are irrelevant. The helper will add droop travel but makes no difference whatsoever to binding.

Also, you are not really using the terms rebound and compression correctly - rebound is not a type of travel, droop is; rebound is an adjustment that controls how droop travel behaves. Regardless, a shock does not care whether you have helpers or not, it behaves the same either way given the same range of motion. The only thing that affects the amount of bump to droop travel is ride height - whether it is accomplished by changing the main spring length, rate, adding or deleting a helper makes no difference.
