max , in general one word .com's are getting the highest click $$$ (just ad a net , web , 'e' or an 'i' in front of the name - for excample eFavor.com, eFlavor.com,eCoffee.com,WebVacation.com,WebHotel.com, ect.. in that case it was eElephant.com (some of these names do not get a large amount of type ins , but it pays quite well since also the click rate is very high.
with way you want to go with your traffic names is what you like best - personal .
come names have large amounts of traffic and a good click rate , but if the click only pays $ 0.02 it takes a lot of clicks to make it worth while.
your very best bet is (in my opinion) get as much GENERIC domains (those will ALWAYS have type ins) you will not get a million visits a day per name , but you alsway will make good money (and you have domain name value , as the value of generic domains will steadily go up ).
hope this helps.
