A hybrid superflex kit will roll and dive a bit less and feel a bit more planted, but wont flex as 'free and easy' as the hyperflex or 5 link. In saying that you can still utilise 12in of travel easily with superflex.
A standard hybrid radius arm will handle better again. But it'll bind when flexing due to the distance between the bushes.
Suspension dynamics are a c#nt. Everything characteristic compromises another characteristic adversely in one way or another
