Shimanos share the same general design language but if you think the Met, Chronarch, and curado share the same frame you need to get your eyes checked. That's not even close to what Daiwa does. In the 2015 JDM catalog they have 4 iterations of steezes (3 with SV spools), 4 iterations of T3's, 3 different iterations of Tatulas... and don't get me started on previous Alphas, zillions, and pixys.
