Bottom board: it needs strength and speed (hard bottom board) and practice chopping (soft bottom board). I suggest you choose the all-round type. Some friends and I use Stika, so we are familiar with Stika. Stika Energy Wood WRB is recommended here, and the licensed product in Katsu Hoshi is about 300 (the quality of parallel imports is not guaranteed).

Forehand: crazy 2 sets of glue (with speed), backhand: crazy 3 sets (softer)

At present, the price of "provincial madness" is around 120, and it feels ok to use.

I don't know much about other skirting boards. In fact, the key to the baseboard is appropriateness. It's nice to play with it in your hand. Personal habits and preferences are different. The above can only be used as reference.
