I use a CK at National League level and would not change it for the world. It is light and fits extremely well, I forget I'm wearing it and have never shied away from a save through lack of confidence in my kit. I agree with other comments that safety must be paramount, especially when at 13 still learning/experimenting with new techniques. I have a son who has shown an interest in GK ( although he is too young yet!) and if he wanted the CK I would give serious consideration to this, although not to say he would definitely get it! It is important the helmet fits and the user is confident in it. There is no hard and fast rule to what you need, there are so many options you will be best trying various styles. In my opinion the PE will be sufficient up until high level hockey, but what is £150 more for protection of the head??
