What does everyone think about these sights. Which one is a superior sight. Which one would you go with and is there something else with the brightness of these that you would recomend?

Impact is way brighter in low light i have found. I can still see them after shooting hours.

Can't say I've tried the impact ones, but the Cobra Sidewinder I have is plenty bright for me, and a great improvement over any "short fiber" pin I've seen, including TruGlow's tritium-backed steel pins.

Do you know if you can get a bubble for the Impact sights? I think the impact sight is the best I have seen so far. Only I kinda wish they came with a bubble. I admit really don't use my bubble on my present sight all that much but it still is nice to have.

The COSMIC by impact archery combined with the NO-PEEP by timberline works awesome in low light(dawn,dusk)hunting situations!

I shoot the Omega XL from Impact with a blue light. Have never shot a Cobra but I love my Impact. Pin stays lit well after dusk without the blue light on.

i have a bubble on my impact

Yes you can get the bubble for your Impacr Archery.I seen the set of sight, bubble and blue light on e-bay a week ago .I don't know why anyone would need the blue light for their Impact sight, because it's plenty bright as Gruhotbigracks said ,I can see my pin as well well after shooting light has passed .I don't know much about the Cobra but I do own the Cosmic from Impact and it's the best hunting sight I've used .

I love my Sidewinder. In my opinion its the perfect site, durable, bright, and looks cool.

Do you think the way the Fiber is strung on the cobra that it will be an issue? I am between these two.
