fiber optic shotgun sight suggestions

[NCdeerguy]

I'm looking to purchase a fiber optic site for my mossberg 835 to help for low light conditions when deer hunting and turkey hunting, ex. truglo, HiViz, etc. I'll be using buckshot on stand with deer, so a front sight may be all I need for that, but for other scenarios, such as with slugs, maybe a rear sight combo. What do you all suggest? I'm focusing on brightness. Your suggestions are greatly appreciated. thanks
