Alpha Crux is more jumpy off the end of the oil. No Rules pearl is very rolly, but more angular off the end off the oil. phase 2 is also rolly but the look almost reminds me of the old particle balls, but with better continuation. Great core shell matchup. If anyone is looking for me to call it stronger or weaker than the other two you won't get it here. There are times when I get a better look from my nrp, and times I get a better look from the Phase 2.
