I'll weigh in here just to say that a slipjoint almost always makes sense. In my case I usually carry three knives (one fixed, one locking folder, one slipjoint). In this way I have a knife to cover all situations pretty much. I like tacticals because I just do. They're fun to carry. However, when it comes to something where I'd be leary of a lock releasing I use a fixed blade. For those times when I'm just dinking around I use the locking folder. However, there are times when a slipjoint is better. Those times include being in non-knife company or when I really need to slice something precisely. There's nothing that's going to get into a tight place and let me do intricate work like a slipjoint. My sheepsfoot blade is the one used the most- which is why I'm thinking about getting a Congress. In short, with as negligible as the weight of a slipjoint is, you can afford to have one on the odd chance that using a locking folder or a fixed blade aren't advisable. Just my opinion, and worth what you paid for it!
