Would like to obtain some Head 18 X 20 MidPlus size grommet sets with Bumper guards. Do not want the "capped" style of grommets as those will be replaced with the new sets. Can trade sets of string for the grommets. I also have other Head (16x19) MP grommet sets to trade including capped versions. Send pictures and notes to jwkeating at sbcglobal dot net. Thanks TT Mods and Members!
