I've been practicing Northern Shaolin Long Fist for about a year now.
Our training consists mainly of stance work, two man drills, and
sparring drills (practicing footwork and combinations). I usually
participate in continues sparring sessions with a couple of the
advance students at least once or twice a week, and when I
do we are usually working with MMA style rules.
Fighting with people who are generally larger than me, guys
would normally be out of my weight class, has demonstrated
to me that weight is a huge factor in any fight. Grappling
though seems to be most effected by it, for it is mainly a
matter of positioning and momentum and as a thinner person
(155 pounds/ 6ft) it can be an extremely difficult situation.

So the question is: How do you feel the removal of weight classes would effect the MMA venue? this is in terms of skill, style, etc.
