Levelling kit caster question

[Bigshow]

I have a Readylift 2.5" levelling kit on my F250 along with 5" rear blocks. The kit addressed some issues by providing a carrier bearing shim and track bar relocation bracket. It uses spring spacers and stock coils which I dont mind. It also comes with shock extenders which I will use until I replace the shocks.
The one area this 'budget' kit did not address was caster reduction with levelling kits as does something like the Icon kit. I added some 2.5 degree caster cams and now have caster in the 2.5 degree range as the kit reduced caster to zero and made my truck want to wander on the road, especially if rough.
My question - how much caster is enough as the stock spec calls for something in the 1.5 to 4 degree range. My truck now handles very much like stock. Are there cams bigger than 2.5 degrees and what are the caster bracket kits I have heard about and how do they compare to the cam approach? Can the kit be used with the cams to achieve more caster yet? What does too much caster do and where is the fine line?
Thanks!

I have yet to find cams over 2.5* which just gets it back to stock. Drop brackets would add back castor to stock soooo then you should have aprox 5*
IMO truck needs 4-6*..only way to get this it seems is 4 link arms unless you like dropping the stock arms with a hanger.

Would you have any links to pictures of some of these drop brackets or 4 link arms? I had an email about a superlift caster bracket kit but have not had time to look into it at all.
The 2.5 degrees of caster is a big improvement over the way it was, but I heard that a bit more will make it steer even better!
