Coin Flips

So I have been playing poker online for about 3 years now I still have the desire to go all on and take my risk with coin flips to double my stack in tournys (early on in the tourny). I don't do it much anymore but was wondering how do you take coin flips do you like them? or do you try to stay away?. Any feedback would be great thanks!

I don't like them a lotta times, other times I just feel the urge to and have a gut feeling of a good ending, lol.

if i have chips enough, i call someones pairs with ak or aq. but if i am avarage or close to payout structure, i tend to stay away. i dont like coinflops neither. nobody likes : ) also sometimes close to payout structure, chip leaders try to steal blinds, i call them too.
