I have most Aneros non syn versions. I like the hard plastic because it is much more slippery than any silicone toys I have tried. I have found that most silicone toys tend to be a bit grabby and not move as much.
Last week I ordered a Helix Syn V because I had never tried any of the vibrating Aneros models and I wanted to try a Syn because a lot of people say that the tabs are much more flexible so they move more, but I have found that the tabs on this model are not any more flexible than the standard Helix Trident. Looking at the pictures on their web site it seems that the arms on the Helix Syn V are much thicker than the standard Helix Syn Trident.
So my question is are the arms on the standard non-vibrating syn models significantly more flexible than the equivalent hard plastic models? I like the MGX so might try the MGX Syn.
