Naaaah i would never buy nextlp for the same reason i would never buy the XTR. Anyway i trust that the turbines ISIS are by far better than the prodigies because we are talking about double price here...and i am not prepared to pay double for lets say 5% better performance/durability/stiffness.....if they are 30 or 40% better then i am game for the turbines.... BTW i have tested the Prodigies together with an ISIS RF EVOLVE bb and the performace was bloody marvelous....
