I thought main and backup should be same blade same rubber wor!
IMHO, 比賽板 is not a good concept
It should be main and backup, i.e. main one is used most of the time for practice and for match and backup is used once in a while to get used to, so that it still can be used without big problem during match...
As wood is wood, no two blade are the same, even same weight.
And rubber condition changes too
By the way, many use Jo Gold as front hand wor, try try?
