Ok heres my two cents. If you wanna be in prober position don't buy an abetta or an alamo. They push you legs forward and set you body out of position. I was giving lessons to a girl with and alamo and a guy with an abetta, I made them both sell them and get new saddles because they put them in bad position, and I find abettas don't fit your horse well. When you look for a saddle, find somethind that will fit you horse perfectly and put you legs underneath you, I wouldn'y get something off the internet if you've never bought a saddle before, but something like this http://www.chicksaddlery.com/Merchan...ct_Code=RK1965
Those saddles are really comfy and they fit the horses well, I have two myself. If you don't like the way they look, try something like this http://www.chicksaddlery.com/Merchan...roduct_Count=2
Notice how both of these saddle will put you in position.
I reccomend looking at billy cooks, I know I haven't ridden a Billy Cook saddle I didn't like (except for their cutting saddles are CRAP) but for trail and pleasure they are great.
