You could try a wood racket.
F200 Carbons are very flexy but probably in the 85 to 90 inch range. A lot of the older rackets have noticeable flex even more so than the mid 1990's PT280/630 which seems stiff compared to some older rackets. The marketing trend has been towards lighter, stiffer frames for some time now even with the players rackets. Most seem too stiff and too light to me and lack feel.
