Any advantage to using the smallest combo or the largest etc, some ppl I've talked to say yes others no.

Does using the lower hole (hinge pin hole) of C-block mean raising roll center and implies reduced steering?
Thanks!

Matt : when you tried the upper hole, did you re-set the droop in order to have the same values when you measure them from the C-Hub (very important). Because, when you use that upper hinge pin hole and not re-set the droop, you will have a lot of front droop, meaning that indeed you will not have any on power steering.
If you did re-set the droop, then i am not surprised either , this hole lowers the RC a lot and it might be too much for the tyres (they may work too much). I tried to use the upper hinge pin hole on the rear, and it didn't work well for me.

I use upper hole hinge pin front and rear for strength reason ( I still use standard suspension arm which prone to break after big hit ). The car will oversteer after you use the rear upper hole hinge pin, but you could compensate it with thicker oil and harder springs at front.

Yes, I reset everything in the front when I tried it, it was actually one of Masami's setups, didn't fit my driving style at all. So you're saying when you use the lower hole in the castor block the roll center is lowered? That was the question.

If you want to raise the RC, try swapping the spacers of the front hubs (have the spacer that is placed between the C-Hub and the hub on the lower hinge pin). Again, the droop will need re-setting, as always when you change the RC (apart from when you move the upper link).

Having seen that, I always use the lower hole and the car works fine for me...

I know why, you got me confused, as you answered the question by saying you tried to use the upper hole... 
Anyway, I leave what I posted earlier, it might be helpful for smoe people...

No hinge pins trying to sneak out the back of the car when you use the rear ones....

Err, if you're having that problem, maybe you should consider using the grub screws that are supposed to go in the rear hinge pin holder
