The thunderline is miles and above hotline. The Crossroad and Fireroad are extremely strong and angular; however, they are also surface specific. The Fireroad is a 3000 pad away from being probably the best in anyones bag; the box surface makes the ball go 60ft. I can tell you how many we've drilled in the shop, people come back and say the ball doesnt hook, we hit it with a 2000 or 3000 pad and the ball comes to life. My best friend (power stroker, 16mph, 450 rpms) has one and loves it after he hit it with the pad.The same can be said about the Crossroad. I have 2 of them, my best friend has 3. All with different drills and different surfaces and they all work. Those two are awesome balls.
The manic and frantic are two great entry level balls that have bred success. However, you are again confusing backend motion with hook. The frantic can out-backend almost any ball, however, it need friction to do so. Whereas, the Victory Road solid will not need as much friction to hook and the motion will be earlier. Thats the trade off for a stronger ball, an earlier motion and less backend. The manic might suffice but in true oil the ball will skid because there is not enough friction, and the core and cover are not strong enough. The Victory Road Solid can be a ball that is great for medium heavy, but I dont like the core/cover combo. The cover wants the ball to hook early and the core wants it to push downlane. It can be a matchup nightmare at times, but at 80 bucks, its worth a shot.
