I agree, you should adjust your throw before deciding wether or not to take the weight ring out
I personally dont like the extra weight, but like Dick said, alot of people might disagree
By throwing a trompo grande, it's going to take some adjusting because its bigger and you hold it differently, specially in the begining (i know i did), but if you have a good boomerang with a normal size trompo, you should be able to adjust
Also make sure you using the string that came with it, a normal size string its to short for a trompo that size
Good luck
