Choosing a new stick

Hi,

I'm stuck between a few sticks, any advice is appreciated.

I quite like the JDH x79TT concave stick, as i've tried my mates.

However I've been told the grays GR10000 is much much better, but i'm uncertain if the extra £60 is worth it because I don't know what it will gain me.

It's £200 on one website, on another it's £162 but it says Maxi composite. Is anyone able to tell me if 'maxi composite' means it is different to the other in any way?

Thanks in advance....
