ok, i've bought a brand new racket. 4 3/8 seemed too small whilst 4 1/2 felt too large. therefore i've purchased a heat shrink (grip enlarger) which will enlarge the handle by half a size. I also am applying lead at three and nine asweel as the handle (to keep the origional balance). my question is as follows: what should i put onto the handle first, the heat shrink followed by the lead tape or the lead tape followed by the heat shrink? many thanks in advance.
