To round out your list I would add the Crossroad and Victory Road pearl. Here is (IMHO) how I think they stack up being an owner of the HY-Road, CrossRoad and Victory Road Pearl.
Crossroad - Biggest core, GREAT power at the pin deck, strong controlled motion to the pins. Least sensitive to carrydown of the bunch IMHO. it hits like a tank.
Frantic - Little longer than the Crossroad and more angular than the Crossroad but not nearly as angular as the Victory Road Pearl (note; Victory Road Pearl and Crossroad have the same core but different covers).
Victory Road Pearl - Most angular on the back end. Allows you to open up the lanes the most but needs dry back ends to flaunt it's stuff.
HY-Road - Tried and true favorite since it's release in 2008. If you spend time reading the threads and opinions on the Hy-Road you will find a fair number of folks say that they love it or find it to be frustrating. I tend to agree in that I find mine to be very condition specific in that it works great for awhile but get's very "jumpy" off the spot when lanes start to transition. I still love the ball nonetheless.
Reign Supreme - have not thrown but I believe it is the least aggressive of the 4 listed but not by much.
I think all work best on medium heavy to medium dry conditions and shine on medium conditions.
My recommendation is to spend a half hour on a Saturday afternoon with a good pro shop operator and let him watch you throw a few balls. Your speed, revs, tilt, rotation, etc. along with your desired ball look will all need to be taken into account to get you the best match up.
my 2 cents.
