I've tried a ton of DI's and the only one I use nowadays is the A Designs REDDI. The thing just sounds huge and fat. You'll need a good pre (I use a 1073) for make up gain and I also mic the 4x10 cab I have with an AKG D12e. When mixing, take out a tiny bit at 400hz and add in some 1k-2k for definition.
I compress the bass pretty hard and then also parallel compress it so it's all nice and even and a main part of the mix.
As long as you have good sounds and good player for the tracking stage you'll be fine when it comes to mix time.
