Nice racquet. I recall this frame being one of about 3 flagship issues from Puma for their final year of newish merchandise in the States, maybe 1988. Another model was called the Top Flex. There might've been a Top Spin too, or maybe I'm just imagining that. Puma was still making the Becker Super viably but had gravitated away from putting Boris's name on every frame, perhaps because the end was near re: their relationship with him. Becker started to wear Fila togs in the first half of 1988. Never found a walk-in shop that sold these models.
