I think the Nomad solid will most likely give you the best look of your current arsenal. In my experiences, smoother arcing control pieces work best. Not trying to FIGJAM but I have a career 208 average out there, an award score, and a 792 set. I have usually had some very good looks. Average would be higher except for nursing pretty substantial injuries 2 of the last 3 years out there.
Anyhow, I have an Attitude Shift (very similar cover to your Nomad) with a shorter pin to PAP layout (around 3") that always goes with me there and to any tighter tournament patterns. It is usually money on the Nationals pattern at 2000 Abralon. My specs are in my profile (we are similar in speed/revs).
If you are looking to drill a new ball I would recommend something with R2S solid from Storm. My Attitude is great and guys were killing it with the Special Agent a few years back. Now, that said this years pattern is a but different but generally speaking over the last few years that cover and the Global Eagle/Break/Break Out have had high success rates.
By going with an R2S solid ball with a shorter pin to PAP layout to compliment the Nomad I think you will have a nice 1-2 punch. I notice most of your stuff is longer Pin to PAP and this helps the ball flip/finish on the back. In my opinion, controlling the heads and mids is what works well out there.
Sorry so long winded....hope this helps.
