I have heard often that straight ankle locks "never work", but they are one of the few leg locks that are legal at basically any competition, gi or no-gi, and they don't seem nearly as dangerous to practice with my team as heel hooks and knee bars.
If they could actually be decently high percentage, they would be worth adding to my competition game, but I don't want to waste my time for too long on a low-percentage move. Your thoughts? Does anyone here use a lot of straight ankle locks, or for that matter, does anyone have luck with some basic foot-locks in 50-50?
Not low % at ALL! Read this article with Rodrigo Cavaca about his ridiculous footlock. He tapped 5 guys with it, 4 times from the 50/50 in the 2010 Worlds.

Just youtube Rodrigo Cavaca for a shitload of straight footlock vids.
The straight footlock is a great sub no matter if it's from the 50/50, the regular leglock position, or the outside leg triangle, etc. It's often said you can judge a person's leglock skills by how good their straight ankle lock is. It's almost as powerful as the heel hook, and it's most definitely not JUST a pain sub like many people think.
Other good footlock guys to watch in BJJ are Braulio and Victor Estima. Braulio broke Rafael Lovato Jr.'s foot in ADCC 09 with a straight footlock. I mean immediately. He did a really unique set up and finish I haven't seen before. Marcelo Garcia actually has an incredible straight footlock from the cross-body position (basically the same angle to finish, but Marcelo does not use the 50/50.) Marcelo wraps his arm actually about halfway up the calf with the toes as deep as possible in the armpit and finishes with one arm.
The key for any straight footlock is the toes. They need to be deep in your armpit so that you aren't simply pinching the Achilles. You'll actually be using your own body mechanics to sheer and tear the foot off of the ankle. That's the idea. I vary between the Kimura grip and the Guillotine grip. I'm using the Guillotine grip more now. Try to keep their leg with a serious bend in it, get those your lat/armpit right on the toes without them slipping out, and secure your arms low on the leg in either grip. It's hard to describe, but as yo do your bridging motion try and flex your lat while rotating your upper body slightly up and away in the direction of the trapped foot. Here's a good example of this motion in the cross-body or 50/50 footlock:
