Java, aren't you doing a cattle management/ranch horse type school/class?
An association saddle like smrobs uses is great, I have ridden in them too. Also a wade is a good ranch saddle and both a wade or association is made for roping and sitting in for long hours. A team roping is NOT. I tried spendy long hours in a team roping saddle and it about crippled me...you can rope out of them but that doesn't mean they are good for sitting in all day :)
