Chapter 2 has a good analysis of shocks.
Cheers for finding that

See it isn't as easy as drill the hole out so i can use up my old 80wt oil and still get a soft suspension set-up

Omg. Its called pack! You do it when you don't have 2 hole pistons. why do you want 2 hole pistons. so you have the same damping as normal for the traction you need but now you can hit large jumps without your chassis slapping the ground. But anyway its called pack, so just read up on packing your shocks.

I have 4 blank HB pistons that I am drilling out tonight. Main reason is I have large jumps on a smooth track and I dont want to keep trying to go thicker with oil and give up traction, same with the springs. I can keep my oil light and my springs stock which are a little soft. They should feel about the same on most of the track except now when the shocks try to compress fast from a huge landing they won't bottom out. Well, I'll know for sure if it works in a few hours.

OK, it is an old topic but still there is no clear answer to me.

My vision:
Most of the time with larger drilled holes a thicker silicone oil is used. Because our pistons have no seal with the shock body it is causing a small leak. The small leak can have a huge influence on small hole pistons. Going to larger holes with a thicker oil makes the leak at the side of the piston less important with the result a more consistant setup/rebuild.
