Since you're weakest ball is the Hy-Road and that is s true medium oil ball, there are a bunch of balls that cover that range and they can be very different from one another. There are balls for medium-light to medium oil balls, light to medium light oil and dry to light oil balls. In an arsenal, at least 2 balls fit in that range for many people.
Can you better qualify your needs?
For true dry, only a polyester ball will do.
There are now a bunch of urethane, solid and pearl, for light to medium-light and medium-light to medium oil:
VIsionary Ogre urethane
Storm Natural
Seismic Desperado
AMf Hype Urethane.
There are tons of pearl resin and a couple of solid resin for light to medium-light oil:
Tropical Storm
RG Neptune
Ebonite Bash
Lane#1 Chainsaw
Morich Mojave
Brunswick Avalanche Slide
Columbia Jazz
Visionary Blue/Green Centaur
900Global Link
Hammer Razyr
