How to pinch a lacrosse Head

There is multiple ways of pinching a lacrosse head, Pinching means to make the throat of your lacrosse head closer together causing your stick to have better hold. I did it this way because my head was already strung.
1.unscrew head and get a hair dryer.
2.tie a string around the throat of the lacrosse stick to the desired pinch.
3.put hairdryer on high and hot.
4.blow dry the part you want pinched the most and just around it for about 5 minutes on each side then after blow dry on each side for about a minute.
5. after immediately put your head in the freezer, leave it there for about 10 minutes when you take it out for best results do not untie the string for about 24 hours.

There is another way but will only work if your head is unstrung, do everything stated above except instead using a hairdryer boil the head for about 10 minutes on medium high heat completely submerged in the water.
