Lower Static Compression With Screw

Kind of an odd question, but here goes..... For those running screws (C or D) at high overdrives, what are you running for typical static compression ratios these days in blown alcohol? Has anyone tried "lowering" their static to say 9:1 or 10:1 'ish (or less) and how did that work out for you? Would like to try lowering our static a bit, as part of a bigger overall project, but I don't want this thing to be a dog when just on acohol.

 

screw over drive

92% over we are running 10.5 to 1 . works very well for our program with a 206D 500 inch BBC
