So I have TTTF for the "lawn" part of my yard (36k sq/ft). It's fairly thick in most places with some really annoying bare and thin areas. I have to sod a couple areas because of drainage issues. I am going to go with KBG because I am sick of overseeing. Question is, if I start plugging KBG, what do you think it's success will be with TTTF all around it? I'm going to go with HGT KBG.
