Everyone loved the original Heat. It was one of the best balls for drier lane conditions. We took that same concept and put a stronger hybrid coverstock on the new Ultra Heat to give the beloved Heat ball motion a little more mid lane grip so that it can be thrown on a wider variety of patterns.
The DR-6 Hybrid is quite a bit stronger than the DR-5 Pearl found on the Heat. Finished at 500/1000 Abralon w Factory Finish Polish, this DR-6 Hybrid cover will give you plenty of length with a strong downlane motion on medium oil patterns.
The Modified Tri-Core is a throw back to the core design found in the original Heat. We’ve matched the RG perfectly to the original while lowering the flare potential slightly to match up better with today’s stronger covers.
