 The QRS fly rail from Graze astonishingly covers 11 line weights in just 3 models. The QRS-1 offers spools designed for 2, 3, 4 and 5 weight lines, the 2 allows for 5, 6, 7 and 8, and the 3 will take lines 9, 10, 11 and 12 in single and double hand options. The 1 and 2 have open cages and the 3 has a closed cage. Upon unboxing you'll find instructions, a reel pouch containing the reel and 3 spare polycarbonate cassettes and the line ID tags. The reel is of excellent quality and the cassettes come in 2 pairs. As seen here the overall diameter of the spools are the same, but the floor of the spool is shallower for lighter lines and deeper for heavier, thicker and longer lines. The line ID tags allow you to mark the sink rate and line weight fitted onto the spool for efficient identification. The Graze rule on this drag system will stop any game species in our UK waters in a single turn. The captive screw in the center allows you to release the cassette and replace it using the QRS lock switch for quick and easy line changes, whilst out in the water or setting up for the day. Simply flip the switch and remove the spool, line up the new spool with the grooves and lock the switch back into position. Additionally, inside the reel simply flip the moulded washer to change your retrieve from left to right handed. This is the neatest system we have seen for changing wind direction and we applaud Graze for it.
