Ultra Cam is hands down the best I've ever used, but the BCY 8190 & the Brownell XS2 are running it a real close second, and may even exceed my expectations of them.
My nod goes to the XS2, but either will do you fine.
Keep the strand count at around 14 with them, and you'll have a moderately skinny, well performing, and stable string.
P.S.
deadeyed - astroflight & d10 are comparable materials, both are of SK78 dyneema.
Neither come anywhere near being as good as the 8190, or XS2 which are both SK90 dyneema, and currently the best 100% dyneema material available.
