Going from 37.5 to 36.5

Hi everyone, I'm currently playing with a woodworm hockey stick size 37.5 I'm used to 37.5 sticks but I have had an offer from a friend that seems hard to refuse.

He's offering me for half the price (70£) the AJ7 probow from Grays (special Ashley Jackson stick) but the stick has a size of 36.5.

I'm a dragflicker and I find it hard to dragflick with the stick I currentlt own.

Should I buy the AJ7 probow size 36.5 at 70£?

Thank you
