I've been edging toward dropping the cash on a set of Soul wheels, but I have to admit that if the difference between my RS10 wheels and the Soul S4.0 is so insignificant that it wouldn't affect most of my riding, I couldn't justify the expense.

Riding style: 200+ solo miles a week.
1-2 club rides a week now @ 50 miles a day
No racing at this point
2-4 century
2 brevets

Looking into doing some local/regional crit racing in the next year, but not on this particular bike.
