Christa Z ~ They're both great options and the Allegro 2 won't be too different for you since you're used to a Studio Reformer. The springs will be the same so you won't have to translate anything. The main difference is the Allegro 2 has an infinity footbar that can move to many different places on the Reformer. Here is a class that shows some of the uses so you can get an idea of it. It can still be used as a traditional footbar though so this is a bonus feature. I hope this helps!
