Amigo XL or Amigo stock horse blanket?

Hi,
I would like to hear experiences from people who have an Amigo stock horse or an Amigo XL blanket for their horse.
My pony is wide and has a very big neck, so I always get into trouble with the neck of a blanket.
Now I have years without necks of horseware (rhino and rambo) and they were good, but the necks are really too tight.
I would like to have 1 blanket with a neck, so I'm looking at the two blankets I mentioned above.
Now I already see that the Amigo stock horse is 600 D and the XL 1200 D. That is a difference.
I am curious about:
the inner fabric of the blankets. Is this the same smooth fabric as the Rambo / Rhino blankets?
the inner fabric of the neck of the blanket?
the blanket really falls well with broad horses and especially the neck is wide enough?
do you have the same size for your horse as normal with Horseware blankets and the same size neck?
how is it with the mane of your horse after using the neck?

Please help.

I didn't find the right solution from the Internet.
