Hey GD -
Quickly - I obviously enjoy them all; however, I feel a good combination of the "above" is very beneficial. Good variety.
They all have their merits - Hugs/Holds gives one a split second longer to act as opposed to a punch or other strike. Chokes/Locks - even less time.
Do I have a favorite - really, it depends on what day of the week it is. I feel more successful in dealing with the Grabs/Hugs/Holds/Locks/Chokes - simply because of the time factor involved. In time, though, in time, my brother - I will be better and faster and more proficient.
Respect -
