I am cleaning up my mid plus frames and I saw some interesting stuff.. I have a few Head Radical Tour which look identical to PRO Tour so I CAP them all up and weight.. here are some pictures The CAP radical Tour & PT630 CAP weight about 320g (no leather grip, no string). Put on string and leather grip, dampener it weight up to 350g. I took them both out for a spin and quite to my surprise both play alot & alot better with the CAP on.. Very stable ground strokes & solid in the volleys.. I felt both are identical in term of playing and feel.. so is that Radical Tour just difference name or the ones I have just a paint job of the actuall PT630.. I will show the overlay pictures of both next..
