We have the Try-angle and rarely use it plus it takes up closet space, we also found the angle too high for us.. We lie our Mini column better and have used it both missionary and doggy style. I'm going to make decorative pillow covers for mine to just leave on the bed all the time. It makes a great back rest for reading in bed too.
If I had known realized from the measurements posted how big it was I would have gotten the mini try angle. I think I even uploaded a pic comparing the Mini column to the try angle on the mini column page. Keep in mind though what didn't work too well for us might work for you.
