Sweat Patches

I was just reading some other threads but I didn't want to hijack their post but when riding and taking the saddle off should the sweat be everywhere where the saddle was, in a perfect shape?
Or would it be okay if it was exactly the same on both sides but it was not the full shape like it was missing the top of the saddle shape?

I'm just curious as Buzz's saddle only sweats leaving a little section with no sweat on it and sometimes when I only ride for a little bit only on his shoulders, well the closest part to his shoulders where the saddle fits.

At Pony Club yesterday we had a saddle fitter come in and talk to us about saddle fitting. I asked if she could check Buzz's and she did, she said the gullet was a little bit to wide but because I had a lot of stuff under it as well (I ride with two saddle blankets and a riser) it was fine.

But when I read about the sweat patches maybe it isn't?
Any opionins would be appreciated

If you put a baby pad under the saddle and ride in it, ultimately what you should find afterward are a clean dry area over the spine and wither, and the rest of the pad should be uniformly wet. It should kind of look like a butterfly for lack of a better shape. It's best to leave the horse a little dirty so you can see what areas are more unbalanced. For example, a saddle that's heavier in the cantle will produce a saddle pad that is dirtier in the back than the front.

What do you mean by baby pad?

Just something thin so it doesn't interfere with the way the saddle fits, preferably white so it shows all the dirt.

Okay, but I know the saddle has a too wide of gullet and riding without everything will cause problems. Wont it?

Or should I just invest in a new saddle with a smaller gullet, but then I have to save up for it

If you know your gullet is too wide, I would not use that saddle. There's no pad that's going to keep a rigid saddle from sitting on your horse's withers. It can do a lot of damage to his spine. In this economy there are a lot of good deals out there on used saddles. Why chance it?
