Please note that you should not engage someone in these styles unawares. Some of our instructors are infirm, or are otherwise suffering form incipient geriatric conditions, and are fragile.
A weapon combination class is similar to "Advanced Sword & Shield" and will cover specific shots, foot placement, set-ups, and alternate or esoteric techniques. In general, you should be comfortable with basic shot placement, the basic selection of shots (wraps, chops, flat-wraps, hammer shots), and basic stance and motion.
A technical class will cover specific techniques or skills which are general to all fighting styles. These classes tend to be more conceptual, and will typically revolve around the mental aspects of fighting strategy.
Additionally, you should look for classes which have few students signed up. You will get more face-time with the instructor. All of our classes are vetted for content, and we do not offer classes which are not an important part of every top-end fighter's repertoire. You may be surprised what you can learn from an overlooked class.
