If you have a cassette where you don't need the big cogs you can remove them and put spacers there. Many RDs adjustment screws will block that nicely. I would avoid actually using the 11 and 12.
Don't have a good pedigree in Time trialing. Road races I usually sit high 80's and I know in time trialling I usually spin just a tad bit faster. Looking at some old TTT data from collegiate last year, looked like I was low to mid 90's, but those shouldn't be indicative.
Valley of the sun looks to be a pretty flat TT, would imagin I'm going to be pushing hard on the way out and trying my best on the way back. I know your son had some pretty good results there. Was that generally his pacing strategy at that race?
