WinWing or Virpil

I currently fly in DCS (Huey) using a Thrustmaster TWCS and a vkb stick. I am looking to get a collective but cannot see either of these in real life without making a purchase. Has anyone here seen both? I’ve a few accounts- the Winwing has that U shaped thing that limits excursion of the collective (to prevent damage) but it also has a different friction in one direction than the other.
