How many hybrids you should carry as a lady golfer really depends on how you hit your irons.
Hybrids are much easier and more forgiving clubs to use than your longer irons so you could carry hybrids to replace these and keep your mid irons and short irons in your golf bag. However, if you struggle to hit your mid and shorter irons well you can also replace these and every iron in your golf bag with a hybrid. Have a look at the Thomas Golf website and you will see the complete range of hybrids that they have to offer you to help you improve and enjoy your game more.
Hybrids are easier to hit as they have a larger club head than your irons do. Because of this a hybrid has a much larger sweet spot than an iron does and striking shots from the sweet spot of the club head produces shots that travel further and more accurately. The bigger the sweet spot is on the club face, the easier it is to strike the ball from, so using a hybrid means you will hit longer and straighter golf shots more often than you would using your irons.
The bigger club head of the hybrid also means that club designers can place more weight around the perimeter of the club head increasing the club’s moment of inertia. Put simply, moment of inertia is the club head's ability to resist rotational force and this is important when it comes to off centre hits. Think about how an ice skater spins. If the skater holds their arms out away from their body, they spin much slower than if they pull their arms in close to their body. This is because the further they hold their arms out from their centre, the higher their resistance is to the rotational force of the spin.
This is true of a golf club head. The further away from the centre of the club head the weight is placed, the more the club head can resist any rotational force put on it. If you strike a golf ball from off centre, for example towards the toe of the club head, the toe of the club will slow down due to the impact with the golf ball. However, the heel of the club head will continue to travel at the higher speed it was travelling at as nothing is slowing it down. The club head will have a twisting or rotational force placed upon it. But a hybrid golf club is able to resist this twisting or rotational force due to its perimeter weighting in the club head design, whereas an iron is not able to resist the twisting as much and the iron will produce a far less accurate golf shot.
The wider sole of the hybrid is also designed to help the club head glide over the turf so that the leading edge, or bottom area of the club face, does not dig into the ground and slow down. The leading edge of an iron does dig in and the golf ball is struck with a much lower club head speed as this is transferred into the ground rather than the golf ball. Striking the golf ball with a lower club head speed results in a golf shot that is hit a much shorter distance. The design of the hybrid club head with its ability to glide over the turf produces shots that fly further as a high speed is transferred from the club head into the golf ball as it is struck.
A hybrid also has a much lower centre of gravity than an iron, the golf ball will be launched at a much higher angle into the air than an iron can achieve. This makes the hybrid a much easier club to hit high and the more you get the ball into the air, the further you will hit the golf shot and the softer it will land on the green.
Have a look at the Thomas Golf website at the huge variety of different lofted hybrids that they produce and if you are struggling to hit any of your current irons, why not replace them for a much more forgiving and easier to use version.
