I got a demo for the MicroGEL Radical Midplus, which I really like EXCEPT for the dense 18x20 string pattern which makes spin generation somewhat more challenging. In a perfect world, I would like the MicroGEL Radical but with a 16x19 string pattern. Is the MicroGEL Extreme (16x19) very different? I ask because most specifications are quite similar (besides stiffness). In other words, once I send back the Radical, is the Extreme worth demoing as well?
