Seems it would be so much easier and more safe to do as Jel suggested. MrYum has a point, but if you have many sites to check, that could take some time, if it would be worth it.
Couple things I dont think submitters always think about is that LL's could have different traffic levels depending on the catagory, though you might not get much traffic for one niche, you could for another catagory. Also, if your doing narrow niches, a few hits from a LL that has filtered the traffic to your particular niche could be worth more than a bunch of hits from a page that is not as targeted.
Of course most webmasters are pressed for time, so you have to go with what works best and what is more productive. Just food for thought...
