Two-Sided JPen — Any Good Instructional Material?

[LeBallski]

Hi everyone. I’m a beginner, and I play with a JPen ( Yinhe 988) with inverted rubber on both sides (Xiom Vega intro FH, Nittaku c1 BH). I find it very comfortable, and I feel confident using it. The problem is that there is a lot of prejudice against this setup in Brazil, and there is basically no proper coaching for it at clubs.


Does anyone know of any instructional material other than Matsushita’s or Araki’s? (I haven’t abandoned TPB completly).

(I’m also doing some research on the impact of this prejudice in Brazil, but that’s another topic.)
