sticks with one significantly heavier edge than the other, thus, when the stick was put at rest, it tilted to one side, reducing the measure curvature. Using this loophole, many stick manufacturers have produced sticks that have bows much greater than 25 mm, sometimes even exceeding 35 mm. If a field player is injured during a penalty corner and has to leave the field for medical attention, a replacement player cannot enter the field until the penalty corner ends. Calum Giles (GB) was noted for being the best drag-flicker during this time, scoring 110 goals in 143 caps. Most national teams have a flicking expert within their sides, with some notable figures including Sohail Abbas of Pakistan, Sandeep Singh, VR Ragunath and Rupinder Pal Singh of India, Taeke Taekema of the Netherlands, Troy Elder of Australia and Hayden Shaw of New Zealand. Generally speed of drag flicks are in excess of 80 mph . History As players became more and more athletic as the game developed, certain shots were made illegal during penalty corners. However, as umpires become more and more strict within field hockey as new discoveries of techniques and training are subsequently making the sport more dangerous while also increasing the pace of the game. Jay Stacy (former record holder for most caps for the Kookaburras) is credited as first using the skill in the 1987 Australian Hockey Championships in Hobart. Along with changes in stick topography, as the drag flick became more prolific, it introduced the specialist drag flicker into a hockey team. In some cases, the drag flicker was not even part of the standard team but was substituted for a field player whenever a team was awarded a penalty corner. As soon as the penalty corner was over, the substitution was reversed. Because of this, it is now disallowed to substitute whenever a penalty corner situation is in effect, except for an injured goalkeeper, who may be substituted at any time. It is evident that the drag flick is becoming more and more popular means of scoring even outside the penalty corner advantage. As drag flicks have become more popular, specialist hockey sticks have been designed to complement the slinging action of the shot. These sticks are notable for their 'bow' or curve. An example of this would be hockey equipment manufacturer Grays International's Jumbow and Megabow range, which featured sticks from their GX series
