Cmind you should research hukif on here and on his other sites. He finished the task of the year in a week. He is in 2012 task of the year thread if you can't find him. He is proof that DILD can work like a boss if that is what fits you.
And it's not just hukif. I have hear from others, that they can have a DILD pretty much any day they want to, but not 100% success rate. And I also heard from WILD masters, that they have high success rate, but not 100%.

It's all just a matter of figuring out, what works for you personally.
