What Aneros should I buy next?

I have had my progasm ice for almost a year now and I am looking to mix it up a little bit, and maybe get something that moves a little bit more. I have been thinking of the eupho for a while now since I see that moves the most but it also has the most suble feeling from what I understand. The helix has also caught my eye but I feel it is too similar to the progasm. What do you guys think?
