I briefly had a 12R5.2 and it had the same tendencies as the Roche. I have also driven an X12 '15 and a VBC in inline and they felt like they had a ton more steering but they also had the rear way freer than I like - snap levels at high speed...but the cars turned if you didn't over-do it. Maybe I am walking a fine line between what works and what I like? My SM has a planted rear however. The only other caveot here is that te SM is a 17.5 car and the Roche is a 13.5 but that shouldn't matter here because corner speed should in theory be the same. High speed entry may change but that's about it.
