Should I upgrade to Dos 1.8.1, Spark 1.6.3, Dialog 1.8.1.54, Phantom 1.8.1.54?

Thanks. Updated. I did not have a choice as when I tried to add a second pair, I could not get past the screen until I first updated. No problems updating and all four are rock solid stable via wireless. Tested also bluetooth - also stable.

I do live in an environment where there is very little wireless interference beyond our own home equipment.
