Maybe its some mystical power at work and its your predetermined destiny to have one disappointingly unreliable race bike to offset the joy provided by another entirely satisfactory and satisfying one?

Is this worse than having 2 "inbetweeners" that could be unpredictably unpredictable in their reliability and pleasure of riding & owning, leading to perpetual nervous uncertainty while riding?

Upsetting the karmic equilibrium by disposing of the unreliable one could be tempting fate. Maybe the solution to this philosophical quandary is to purchase a third race bike?
