I don't know much about this racquet, but I just bought a few... How does it play compared to a Prince Woodie or a Jack Kramer Midsize? What is the flex rating? How flexible does it play compared to other wood racquets or something like the Rossignol F200? Did it come in different weights, or were they all the same? When and how long was it produced? How difficult is it to find this one new?
