I have several of each (Cumara, Carrot Stix, and GLX's). Honestly, the GLX is the best rod ever - just for quality - but you pay for them. However, they are all just as sensitive. I prefer my Carrot Stix gold to my Cumara. There is little difference (IMO) from the standard Carrtot Stix and Cumara - I prefer the carrot stix to the cumara.

If I had the money, I would get a GLX, without hesitation. However, a close second would be the Carrot Stix Gold edition, but would not be disappointed with the standard Carrot Stix or Cumara - but for the $50 + price difference in those two the carrot Stix is the way to go. Since the cumara's and Carrot Stix Gold series are the same price, I would definitely go for the carrot stix gold.
