Horizon Solid won't be a true oiler, more like a medium-heavy solid reactive with decent backend recovery and continuation...kind of like a Black Widow but less angular...a nice all-around ball that should work well on more trying, higher volume patterns...
Quite simply, it's not in the same class as the Resurgence (but I'm sure you already guessed that). Additionally, if I am correct in saying that you are looking for a quick-revving solid that will handle most longer and oilier patterns, without being "just" a flood ball, I would've suggested a 900 Global The Break or a Roto Epic Odyssey, but you specified that you wanted a symmetrical core...sorry to say, but there isn't much out there in terms of low RG symmetrical oil balls. I mean, there are some mid-high RG balls for medium-heavy, like a Hammer Anger or Storm's T-Road Solid, and then there's the Horizon Solid...but all of those offer that "in-between" look, and aren't quite the monsters of the oil-handling scene.
Also just thought of Brunswick's Fury, which might be another option too.
Honestly, though, what's the matter with asymmetricals? If you were open to them, you'd get to toss both the Break and the Odyssey into the picture, both of which I think are great balls for heavier oil...with the Resurgence being considered as well, I don't think you could go wrong.
Hope this helps.
