The Soul is a great ball that handles oil very well. I would say it will be a nice step up from the nano pearl and handle oil better. I also have a Nomad Solid and there is a big difference between the two, I have a ball in between those two. The Soul has been great for me, I have drilled 50x5x40(pin up) and it reads the mids great and has a strong finish. I have a few friends that have the Nano pearl and to be honest I am not impressed, I have a nano which is great when there is a ton of oil, but the pearl doesnt impress me, just my opinion.

My self have a Nano pearl and love it for med to med-heavy go to my defiant for more oil. Why no love for the Nano pearl Duva?

I do like the Nano Pearl, and have shot some great scores with it.  I just need a ball that is a bit stronger with good backend to it.  I'm liking the way the Soul looks, and from everything I've read, it seems to work well for a lot of styles on different patterns.  I might have to think about trading my NIB Hell Raiser Revenge in for a Soul.
