If you have a club that you like and it performs for you, why not just stick with it?
I have a max spin 64 wedge that I've had for ages, tried the L91 version of it last week and went straight back to the original because I know exactly what I can do with it, in fact I call it my magic wand, it's got me out of so much trouble over the months.
now I won't buy a club that I haven't trialled first. IE I bought the Versa putter on others recommendations, hated it, and went back to my ghost
