I don't recall using spoilers or not with my ASW-19b (CG hook), but I
always used spoilers and negative flaps with my LS-6a also a CG hook)
and found that to be an improvement. I continued using negative flaps,
but no spoilers, in my LAK-17a (CG hook), and had no problems there, either.

In Chip's case, I agree with his assessment that the main cause of
trouble was the partial ballast load shifting outboard on one side
(inboard on the other).

I flew hundreds of hours in a CG hook Pegasus and never used spoilers during a takeoff. No problems.
