Good morning, I was fit for C16 irons last summer by Greg Larkin in Birmingham, AL. I also have the C16 driver, 54 degree and 58 degree Wedgeworks Vokeys, & Cameron X5 putter? They are the best irons I have ever had--even better than the 690.cb. I wore out three sets of those. I recently purchased a replacement 8 iron and wedge with the Nippon 880 shafts. The new irons do not have the back weight in the Tour Velvet grip. I would like to purchase two of the original back weights. If they are no longer available, can you tell me the weight of the 8 iron and wedge weight?
