I have a GP for my 4yo, I went for the Monarch because I wanted changeable gullet and I found it the nicest out of all the changeable gullet ones out there. Its also very comfy, I can hunt for hours in it.
Are the gullets easy to change and what sort of shape is your 4 yo if you dont mind me asking? We have a low withered but stocky conni. What is the quality of the leather like?
I don't know how easy they are to change I'm afraid, I haven't tried.
My 4yo is a KWPN but with not much wither, the leather is good, not amazing but v.good for the price.
