I think Frank is just trying to build up his team right now.. not necessarily the Razorclaws but his regular group of guys for Team Shamrock.
He charges people who are just the "general public" or have no fights for the tryouts.. but if you have 5 or more fights.. then it is a free tryout.
I was able to check out the last tryout just as an observer and it was intersting to watch. I had always heard the Lions Den stories about tryouts.. this was similar but different.
Rather than being militaristic.. by telling them to "give up now".. or "go home" like in the LD stories.. they were very supportive.. and were very positive in comments.. and encouraging them that they could do it.
he drilled them to see what moves they knew... and for cardio.. he would time them.. a minute of pushups.. a minute of situps.. etc.. that just kept going on and on with different exercises.
then they later padded up and did subs, boxing, kickboxing, and then mma.
Maybe Vince Lucero might be able to describe what practices were like and how it compares to other places he has trained at.
