I'd go triangle because it's effective against white to black belts. And its a fairly safe move in that if its a new person or someone you don't know if they freak out a little bit nothing should be breaking.Lots of different set ups and positions it can be done from. Unlike joint locks where flexibility can come into play, if done correctly they are tapping or going out. 

Advanced gi will continue to look at the Aoki lock. We introduced it last week and will look at how it can be applied this week.

Quickly becoming one of my favorites!

I need mix. I need to hit the reps to understand the movements. Once I have some level of understanding I like to add in varying levels of resistance to see if I can actually apply it. Once applied it'll float around in my memory. 

I try to visit 1 different gym a year. I've only been able to make it to 1 out of state. Can't say it was a favorite though.

Like everyone said, call ahead. Some places will have gi requirements that can be color or patch related. It's also nice to know if they will have a drop in fee so there is no surprise there. Some schools don't always have up to date schedules posted. If you aren't sure when you get there it can be a good idea to ask about their etiquette when it comes to things like leg locks. Some places do them and others don't.

Often not discussed if you are an upper belt be prepared for some tough rounds. You might be on vacation, but in some (not all schools) you will be looked at as a challenge or way to prove something. I'm fairly certain we've all done this visitor at some point.

Lastly, have fun!

This week advanced gi continues from our single leg x, ashi or ashi garami position shifting focus from the straight ankle lock to the aoki lock. 

This particular attack has become one of my favorite for the lower body as it can be applied when our partners attempt to utilize several common defenses for the straight ankle lock. 

Gary Pond fair point!

I've heard left over coffee added to dark gis also kills bacteria due to the pH. Never tested it.

Gary Pond why do you publicly asked to be wristy locked? 🤣

I've used that before, it works!

I think I inadvertently have done this. Normally, I'm looking for specific techniques and looking back the instructors I have gravitated toward are normally similar in body type. I think the times when they aren't similar, I'm seeking them out for their knowledge on the topic.
