Which model for an Aneros “newbie”, but experienced with other toys.

I started getting into butt-play about 6 months ago, and really love it. I started with w small plug, but have worked my way up to a medium sized plug. I takes me a while to warm up, and get it all the way in, but when it is, I love the full feeling.

I would like to get my first Aneros, but am struggling to figure out which model to start with….the Helix, since I'm new to prostate stimulation, or the Progasm, since I've already worked my way up to bigger toys…..

Thoughts?
