Have to agree with Juggernaut.
It's one of the mildest balls I have ever seen. As such, there's little likelihood that they'll do a solid version. However, they had several versions of the Power Groove in pearl for both dry lanes and for starter bowlers, before they also issued several other varieties of the PG, including,
1. a solid particle
2. a particle pearl
3. two versions of the solid resin
So, while I wouldn't hold any hope for a solid version, it's within the realm of possibility while not being a probability.
