Think about how runners wear weighted braces/vests in training, then when you take them off you're greased lightning. i think this is the way no-gi oriented people like myself should look at the gi.
+100 to this. The "greased lightning" is probably the way I'll be describing the feeling now of training in a gi vs. someone without a gi, then taking the gi off and fighting pure no gi vs. no gi. I've also used "like a fish back in the water" to describe it
For the skeptics out there, try it. Put on a gi and let your partner (not wearing a gi) use all the grips they want to use. You will notice habits / holes in your game you otherwise didn't think you had. Then, take the gi off and notice the improvement. I found that I was much more precise and methodical in my no gi passing game. This is one of the best ways to improve your guard passing game IMO.
