Being an early adopter of NBG99, I've stuck with NBG99 JP but it's really causing a dent in my wallet. I know there was an earlier post asking JP vs SP but no one has really asked about EX version. Previously I've used NBG98 JP, SP, and CH. Personally I've found the CH is to dull and lost tension EXTREMELY quickly. Also SP and CH strings ACTUALLY break on me. So far with NBG99 JP, I haven't broken any of my strings but it just got really loose on me and I can't play with it without getting hurt. Anyways, I see that Stringers World sells NBG99 EX in reel of 200m and the price is really attractive. So I'm here to ask, how is the EX different from the SP and CH?
