Not quite sure what you mean by a three point arrival but a three point landing usually works well in the Spit and is generally recommended.
As for the pitch and roll control, I agree with what you say. Remember that the speed range in the Chippy is from about 50 to 120 Kts (roughly) so not much variation in the control loads. In a Spit the speed ranges between 70Kts to 300 so yes, the ailerons get pretty heavy at higher speeds.
