The gear is like any other gear,...... who uses it and how its used determines its value. The gear is a great asset to mma training (hermes franca, kurt pellegrino are some) as well as personal protection training and law enforcement training (west palm beach police, jupiter police, palm beach police, PB Sherrif Office, etc). The Armory has used it for all of those markets and its a great tool. You dont necessarily need the whole suit, which for some people/gyms could get costly, there are components that can be purchased and are very useful.
The best use of this gear in the mma world, since this is what this forum seems to be about is that it allows professionals to train more intensely and it assists in insulating against injury but the fighter still feels the pressure, impact is somewhat muted but it still effects your reaction, timing, countering, etc...because if you arent feeling the pain, its going to screw up your realistic reactions.
A piece of gear should enable a pro to train a little harder or a little longer and reduce his/her chance of injuries. This way they get more reps in and get to work on the nuances of timing, details, stuff like that. This gear should not be put on just for 2 people to beat the shit out of each other, instead you can come up with small aspects of the fight game that occur very regularly and work thru those specific moments in fight that may make all the difference in the world to its outcome....
Designing drills practicing a tactical defense/counter of elbows against someone like Louiseau while being folded against the cage (elbows / headgear with shield for face)
Designing drills for leg kicks from Anderson Silva or a clinch from Silva with knees (chest protector / leg girdle)
The High Gear is just a tool, like any other piece of mma equipment, expensive, sure, worht it....depends who is using it and for what purpose.
We are big fans of it.
