Eupho Trident Syn or Helix Trident?

Previously I’d tried various methods to find my prostate but I’d never been able to feel anything noticeable.

Thus I decided to get some help from Aneros, but which should I go with? The Helix have a much larger head but I’m not sure is it gonna have any significant difference in experience compared to Eupho.

Also, Is the ABS plastic better interms of durability compared to the Syn?

Thanks.

Helix or Helix Trident?

Had been struggling for the past few days, which should I choose?

I see a lot of people recommending to modify Helix by shortening the tab at the back, but how about Trident?

I’m just afraid that the fork shape of the Trident would reduce the movement when I contract the PC muscle, but at the same time, it seems it’s fine to sit on the Trident so you can just manually rock yourself?
Most of the site says Trident is a direct upgrade to the Helix.

Thanks in advance.
