Optimum compression for woods TW6Gs?

I am running a set of Woods TW6Gs in my 2005 Dyna and am going to upgrade to 98 inch very soon. I want to keep these cams but would like to know optimum compression for them. I ride solo most of the time, weigh 160lbs and live in New York. The head porter I am using who has the 98 inch kit has two kits. One is 9.5 to 1 and the other is 10.5 to 1. 9.5 to 1 seems kinda low to me but I am worried about detonation issues if I go 10.5 to 1. Should I be? Any help would be much appreciated. TIA, Dave.

The TW6 is similar to the Andrews 37. Andrews recommends around 9.5 for the 37 so my guess would be to go with the 9.5:1, but your head porter should KNOW the answer to your quesion.
