Greetings, everyone: Recently acquired two of the aforementioned racquets, and would appreciate some guidance as to the chronology and playability of these frames. Specifically, one fades from a blue/black to a throat area that is predominantly gold with purple/lilac writing "Vacuum MidSize Pro." The Other has more predominant black markings in the hoop, with a throat area that is predominantly gold/black with "Pro Vacuum MS" written in largely white font enclosed with a black square-type design. So, which one came first? Which is the "Stich" racquet, and is one more sought after (from a collector's or playability perspective) than the other. Appreciate your guidance, as I want to try this racquet out ASAP! Thanks again, all!
