Try http://www.isakbilliard.com. They have shops in Surabaya and Jakarta. Don't know if you want to pay them a visit in person, but their webshop looks decent. Selamat.
I had a WX900 wavy joint and now playing with WD700 (oldWX700) with SS joint. I preferred the softer feel of the WX900. The WD700 plays a bit too crisp for my taste. I regret selling that WX900 shaft. damn!
Could you share your opinion about the Hybrid Max? I have a g2 med on my wx900 and im fine with it, but need a new tip for my wx700 on my older Schön. Thanx
