Here comes the problem. There are absolutely no saddle fitters in my area. There might be one (they own a saddle shop where they make custom western saddles), but they know absolutely NOTHING about English saddles. The closest saddle fitters are 90+ miles away and would cost me $200+ just to get up here...something I obviously can't afford (obviously since I am looking at $200 tack sets on eBay

).
Neither of the saddles the trainer at our stable has fits Aires...not evenly remotely. I'll have to take a pic of them and show you how small they are for him. The part that is supposed to sit on his shoulder literally perches on his withers. There are two other English saddles at the stable (belong to a boarder) and both of them are the same size as the trainer's, so I know they don't fit him. Literally every single other saddle at the stable is a western saddle, with the exception of the trainer's endurance saddle. There is a synthetic western saddle that fits him PERFECTLY (I am pretty good at fitting a western saddle...had a lot of practice with my old gelding), and that I can lift without any problems, that we are going to use for trail rides.
What I really want is a saddle for schooling him in the arena with. I want all the English cues and such to be second nature to him by the time we get to competing in a couple of years (may do some W/T or W/T/C shows in the meantime to get experience and such). There's a lady that comes and overnights at our stable who has a complete Stubben tack set (saddle, bridle, girth, etc) for $400, but I'd be willing to bet it's a medium or maybe medium wide tree. I haven't seen it, but that's basically my luck. I know I need at 17-17.5" seat. The seat on the saddle the trainer was going to loan me was a 17" and it was perfect.
