So the JC foams are not great but the tires are a bit more aggressive, according to most of you. It also sounds like I can expect a bit more forward bite with the Stackers. Great info guys!
The Proline Diamondbacks seem interesting. It would appear they seem better suited for tracks with a clean and grooved driving line since the pins appear closer together than Impacts/Stackers/Blockades.
Any truth to a rumor that JC tires are made in China? Just curious.
