Any experience with the 3S custom equine pads?

My stingray is too wide for my colt so I've been looking at pad options. 3/4" 5 star is way too thin and 1" 5 star is ok, but I'm looking at other options as well. 

If a 1 inch pad isn't having your sddle fit then you need a different saddle with proper fitting. I wouldn't put anything thicker than a 1 inch on a horse and expect it to be comfortable with a ill fitting saddle. 

I agree. I definitely don't want anything thicker than a 1." The 3S pads come in 3/4 and 1" but they have a different wither relief on the evolution pads that could help with fit possibly. The saddle doesn't fit that poorly, she just hasn't finished growing so she's not filled it out completely yet. Edited to add - it's not a crazy big gullet like some Martins are - it's a 7 inch.

Just added saddle photos to my other thread about Robbie Phillips Saddles vs. Stingray.
