I will begin by saying my knowledge of equipment is limited, so bear with me.  

 

I currently have equipment for heavy oil (Nano VG Solid) and light oil (Emerald Vibe).  I'm looking for a ball that is well suited for medium oiled lanes that would be a good complement to my existing equipment.  I would be using this in a THS for the most part, however I do bowl the occasional tournament as well.

 

I've become a fan of Storm recently, and have been looking through potential options, but am having difficulty determining what may be a good fit.  The Frantic and Victory Road Pearl caught my attention, however I'm afraid these may be relatively close to my Nano, and as such may not be a tenable option.

 

My ball speed is approximately 15.5 MPH, however I don't know what my rev rate is, though I've been told it's above average.

 

In case it's worth mentioning, I'm most comfortable playing an outside line between 5 and 10.

 

Can anyone provide suggestions or advice?  I appreciate any help you can provide. 

There is a huge gap between a Nano Solid and an Emerald Vibe.  One is an early rolling solid and the other is a mid to late rolling pearl.  I'd look for something dead between the two from a cover and core perspective.

 

Best bet IMO is to look at a mid-level hybrid.  Hybrids give you the best of both worlds; easy through the heads and more arc / less snap in the backends.  Your Storm / Roto choices there would be a Hyroad, Crossroad, and a Nomad Dagger.  Given your description of your shot I am assuming you are a medium speed, medium revs. stroker.  For that type of bowler I'd recommend a Hyroad because it is the rolliest of the 3.  You can't go wrong with any of those hybrids though.
