I'm not an expert pie maker, by any means (which is why the piecrust recipe in my Better Homes and Gardens Cookbook is violently x-ed out). I just this year really got decent at making a crust. But I always use a pyrex pan, and I've never had a problem with soggy bottom crust. And the recipe I found that works EVERY TIME for me is from the Pioneer Woman Cooks blog. It's very flaky, and can stand more overworking than most, which is important for any piecrust I'm going to make.
