Whats the most crucial aspect to consider when selecting the Jaked JK-2 for a high-level competition, and why do so many riders overlook the importance of proper fit in relation to their specific body type, instead opting for a generic approach that often hinders their performance, and what specific adjustments can be made to the JK-2 to optimize its aerodynamic capabilities for riders with varying physiological characteristics, and how do these adjustments impact the overall efficiency and speed of the suit, and can anyone provide concrete evidence to support their claims, rather than relying on anecdotal evidence and hearsay, and what are the potential drawbacks of prioritizing aerodynamics over comfort and flexibility, and how can riders balance these competing demands to achieve optimal results, and what role does the JK-2 play in this delicate balancing act, and how can riders ensure that theyre getting the most out of their suit without sacrificing other critical aspects of their performance.
