Let's discuss this. Hy-Wire is a polished hybrid and the Rocket Ship is a sheen 3000 abralon finished ball. So obviously the Rocket Ship is going to want to pick up a little earlier than the Hy-Wire. Hy-Wire is also a hybrid that is more pearl than solid composition so again longer and later move for the Hy-Wire.

Hy-Wire specs are 2.50/.43 which are more of a low-med RG and a med diff. Not the high end RG and diff specs but exactly what you want in more of a controllable higher end ball which the Hy-Wire is.

As far as fitting into the bag, Rocket Ship would be a good place to build an arsenal outwards from. R2S cover on a 2.54/.46 rg & diff ball. Dynamics that are closer to the middle of the road as 2.54 would be considered in the lower end of medium RG.

Right now I have the Rocket Ship staged in my bag as my benchmark but also my ball when I need the ball to pick up a little sooner in the mids than my medium cover balls. I also like to ball down to the Hy-Wire when I need some more push thru the mids but still need that good motion on the back that a pearl type ball provides.

If you can pick them both up, they would make a pretty good 1-2 punch in the middle of any arsenal.
