Valve Index Controller issues

Hey i play on Valve Index with the controllers, and i bin having a big major issue like it all works well but sweat and stuff makes it like using your phone in the rain as the way too pickup Gun or Throw Grenade, is using Haptic instead of the built in GRIP strength thingy, making it like stuck too my arm or sometimes my hands stuck in a grip state and i can not Equip my GUNS or Throw a grenade making it just fall and kill me or when am driving and i can not grab the steering it's bin many times where my deaths has bin caused by the Controllers

it's bascially like using a phone out in the rain
and makes many things hard too control or use

please add like a way too use a Grip instead of Haptic as it's a major issue for me.

[I recently started playing and i love the game and the community just the Controllers being a issue is the only thing ruin it for me everything else is great :D]
