Nickent's 3DX RC+ Combo Set features three club designs: ironwoods to replace the 3 and 4 irons, wide-sole mid-irons, and short irons with a narrower sole. The mid and short irons feature carbon backing to dampen vibrations and to lower the centre of gravity, while XW tungsten-polymer weight inserts boost the club's forgiveness and stability at impact. The clubs have True Temper ST-90 steel shafts or UST SR2.5 graphite.
