found a Donnay Pro Cynetic 12 the other day at a charity shop.
it was quite beat up and dirty, came with a dirty full cover too. gave it a wipe and added a leather grip. kept the yellow string (syn gut, i think) and the blue "D" weight at the end of the butt cap. The blue weight felt quite stiff to turn, so kept it on.
i read this is the Pro Cynetic 1 with the wights for butt cap and 3&9. there is a plastic piece on the outside of 3&9 on both sides, but not sure how the weighting system works at 3&9. this is a made in Belgium version, but no code to be found. there is a "37" number on the handle though.
quite cool to have a this as the same mould as the PC1 used by Pete Sampras in his earlier days.
the current measurements are 357.5g/31.6cm - very different to the TW PC1 specs... lol
didnt bother with the SW and TW as i couldnt remove the blue weight at the butt cap. anyway, here are some "clean" pix.
