Is there a fundamental difference in the string tension you should use to play nylon as opposed to feather? And what type of racquet would u go for? a more head-heavy type? or do u need more of a control racquet for the nylon game?
Personally, I don't think there's a difference in racket itself when playing with different shuttles. As for tension, I would like to lower the tension for nylon shuttles (by 10-15%). Also, try to avoid thin strings (i.e. BG66, BG85, etc), as durability might be an issue.
There is no "best racquet" for anything, but you should use durable strings for plastic shuttles. Such as BG65 or 70Pro is fine. People just kept on asking "best racquet for something"......and it's getting annoying because there is no answer. Everyone has his/her preference.
