I knew I shouldn't have posted without photos - I took my camera to the barn and completely forgot about it. I am not super sharp on Sundays, let's just say...

I'll get some shots tomorrow and post them - I need some action shots of me riding to see what sort of position I'm getting myself into, anyway!
SilverLexi - it really was neat to experience everything people on here had told me I would. And in a good way!
Seerfarm - I have runner's knee so my Western saddle makes it sore pretty quickly. I rode for over an hour on Sunday, which is a long time for me in this heat, and didn't even notice my knees. My mother said I looked a lot more relaxed and balanced, despite the fact that I was sitting a lot more upright - I think riding English for so long as a child/teen had just made it easier for me than the Western style. I'm not sure if Romeo was cooler in this than the Western because I was using an English pad (got an Aussie on order now) and it was around 95 degrees so he was very sweaty anyway. But for once he was less wet than my mother's horse, who was literally dripping, so maybe this is good!
Beckyp - it was the suggestions of people here that I bought the Aussie and I am definitely grateful to them for all the advice they gave!
rm185 - I got a hornless one - two reasons - one, I wanted a saddle that was more English in styling, so no horn and the narrower stirrup leathers, and two, I got my shirt and/or bra caught on the horn so many times while trotting and loping in the Western saddle, it was totally unnecessary and indeed rather impractical!
Noni - reading of your experiences with Tango and how you felt secure in the Aussie was definitely a selling point for me. Romeo is about as bomb proof as they come but he is still a horse and therefore will still do "stupid horse" stuff. He very rarely spooks and it's usually a step or two sideways. This was only the second time he's really panicked with me on him. The first time, I was riding in an English saddle on the trail, it was windy as hell, and someone galloped up behind him - he didn't hear the horse coming but when he saw it, he shot sideways faster than I thought possible. I came off and landed on rocks - I tore a rib muscle, bruised the heck out of my back and hip, and impaled my helmet on a small rock. Had I not had that helmet on, the paramedics would have been pulling the rock out of the base of my skull. This time - we watched the horse galloping up the path and Romeo was fine, but he turned his head, lost sight of the horse, and then when it came up behind him - hello! Freak out, shot sideways, then backwards - but I never felt even remotely unstable, which is a testimony to both the saddle and my one-year-on riding ability...
Lady_MCSE - hopefully you'll get a buyer for your saddle who's as enraptured with their purchase as I now am!
Logan - I think transitioning from Western to Aussie is not easy, especially if you've never ridden English. I feel that the Aussie set-up is much closer to English than Western. Having said that, I know there are more Western-inclined Aussie saddles out there. I think
Melissah on these boards purchased one that looks more Western than English and possibly it rides more Western too. I do love the more flexible riding style of the Aussie - the free-hanging stirrups make it so much easier on my knees and ankles, and the deep seat really helps me sit in a good position, right over my seat bones, instead of on the fat part of my butt! Also, as with all saddles, some are better than others. I've ridden in very uncomfortable English and Western saddles, and super-comfy ones - it's just trial and error, I think. Give it another try if you get chance - you may become a convert!
