Jeff, your plane sounds like it behaves similarly to mine when testing aggressive slips at altitude. As long as I approach stall in a less than super aggressive fashion, even in a full rudder deflection slip, the plane gives plenty of warning and barely drops a wing if at all. Reducing back pressure recovers and I can even stay un coordinated through the recovery right back into a slip. I haven't done any very aggressive pull ups but Im sure those might get more exciting. Ive done these with both full flaps and half flaps. I do notice with full flaps the break is more defined.
