That's a good question Mark.
I don't know how the gurus in Holland would approach it but this is what I do on my 705.
I forgot to mention that on top of all the things I do like caster, sway bar settings, tires, I play around with the rear downstops to get better steering on smaller tight tracks.
If I cannot get enough turn in on the the tight corners, I'll change the droop on the fly on the side track itself. No, I don't put it on the setting board. I guess I'm too lazy.
This method proves to be quick and successful for me. Usually, I'll take my Hudy 2 mm allen on the trackside, pick up the car and from the bottomside, I give the downstop screws like half a turn clockwise on each side. Make sure they are equal turns on each left and right. I run my car again to see the difference. Not enough? I pull the car aside and do the same to get more rear droop so that more weight transfers to the front. I usually will do this trick first before attempting to change the caster as I like to keep the caster angle big in order to have as much on power steering as possible. Also, I like how more caster gives stability down the straights if required.
So the general setting I end up for smaller tight tracks is more rear droop (approx +4 or +5 thereabouts). Perhaps this is because like the caster setting, I like to stay with a slightly tighter rear diff to give me good on power steering out of the corners whenever I like it. Small or large tracks alike. I have never played with the front droop. It always stays at 0. My 2 cents.
