QR-4 Solid – We made a slight modification from the QR-5 Solid cover found on the Heat X-Treme that would match up better with the Track Symmetric core we have in the Tundra line. By combining this modification with a 3000 sanded finish, this sanded coverstock doesn’t fight the front of the lane whatsoever, but still gives plenty of traction on light medium oil conditions.
The Track Symmetric core is a super high rg, low differential core that will be a must in any tournament bowlers bag. A core with unique numbers like this will allow the core to store energy longer while remaining smooth and controllable down lane.
When the lanes are on fire, put them on ice by pulling out the new Tundra Solid. This core/cover combination will provide ultimate control when you need it most. Whether you are bowling on old wood lanes, lighter volume oil patterns or on lanes that just flat out hook, the Tundra Solid is the ideal ball for you.
