Isuzu Mu suspension tweaking continues

Since I have lifted the rear and wound up the torsions in the front, the ride has never been that great...
I have removed a leaf from each of the rear leaf sets to soften the rear which has more or less sorted that, but the front remains quite hard.
When I removed a leaf from the rear this dropped the back slightly which ment I could unwind the front torsions (local garage had them wound hard against the upper bump stops so I was on rails!
Now I have had front upper bumps stops cut and the front diff has been dropped to sort the cv angles.

I need to find out if there is any way to get the front softer for small bumps (everyday driving).
The way I understand it is: when you wind up your torsions you loose the initial sag they had and so they end up initally stiff to small bumps- but work on larger hits.
In reading about winding torsions vs heavy duty torsions, it appears that heavy duty ones would be softer if not wound vs wound stocks (both increasing ride height)

What are your thoughts?

I also have a 2" body lift kit that I was thinking of installing in the hope that the leverage from raising the body would soften it a little...

as ive said i have a 3 inch suspension and 2 inch body and mine rides like the day i got it factory, have just fitted calmini top a arma which has made the ride even better and more suspension travel, heavy duty torsion bars will give you more lift without bottoming out the thread on the adjuster bolt, aftermarket torsion bars dont flex as good as factory torsion bars though
