D8T PPR was my favorite. yeah the smaller tracks are no fun but now came out about 3years ago now they have track call PPR2 tracks for D7F / D4k the link is stamped to the track pins to help keep the pins walking out the links when working in heavy Rocks and rapping.I think the links with the ppr rings was better depending what you working in you could replace the pins/Bushing after a turn but the PPR2 links you only get to turn once .
