I have played USTA Open tournaments (circa 1987) with both the Graphite Pro and the navy blue (1987) Club Pro. The Graphite Pro was the stiffest variant Head made in that mold; the Club Pro was the most flexible. It seems there was a slight difference in feel between the navy blue 1987, red/orange 1988, and silver/blue 1989 Club Pros; I think it lies in the different plastic durometer used in the grommet systems (the later white ones being more brittle and harsh). Out of all the “box beam” Head Pro variants, I liked the 1987 Club Pro and Team Pro the best; they were cheaper racquets, but well made (in Austria) and had great feel and power. Only drawbacks I noted (as a USTA 5.0 at the time) was that one couldn’t string them too tightly, otherwise they’d “potato chip” like the Dunlop Max 200g also tended to, and that when playing a very hard hitter, it could be a challenge to accurately redirect the power in a heated groundstroke rally. With the added flex came extra feel, but a loss of control. String it tighter, like above 60 pounds, to enhance control, and the racquet would warp. I went through a bunch of them during the course of a season, then switched in 1988 to the new Elite Pro and was quite content until I started playing Fischer in 1991. Today, I still play mostly with the Elite Pros, which were a slightly more flexible and headlight version of the Prestige. I did playtest the Prestige, and have had numerous Prestige Pros and Prestige Classic 600’s, all customized to my favorite specifications, but just never felt perfectly in synch with them. The Comp Pro you mentioned was a popular frame in its time, but I also didn’t find them to my liking... sort of a “reverse Goldilocks” situation, where on paper it should have been “just right,” but was characterless and flavorless, with better racquet options (for me) available elsewhere in the Head lineup.
