OK, I just bought a new wing for myself for the holidays. This is the third wing I have purchased, and I think I finally have exactly what I want. The only thing I am not sure about is the pull dump feature or lack of one.

On the first set of wings I bought, Dive Rite Dual Super Wings, both hoses had pull dumps. The second wing I bought were Dive Rite Classic wings, they did not have a pull dump, rather a standard elbow. My newest set of wings are a set of OMS non bungie wings, they also have the standard elbow. Now all of these have an inflator/deflator and all have a backup pull dump down low.

My question is what is the reason NOT to have a pull dump on your inflator hose? The other question is can I change this over without replacing the bladder?

I know there must be a reason they offer these both ways, and cost is most likely not the factor as these are not expensive parts.
