Aside from being heavier are they larger in that they have you outreached as well?
I always found that was the harder thing to get around, than just the added weight.
Your footwork takes you around the long road to compensate the reach and their pace and weight as a whole threat.
You find your disrupting your own natural patterns.
Sometimes theres a possibilty to give yourself added room but then take their punches at their elbow line as they come in, so that you are automaticly back into your reach with a disruption of their pattern .
You have come through their expected reach at that point; its nice to practice, cause you are set back into your distance as they are reacting to something unexpected.
You can attack it or just simply check it ;or control their arm,and attack them bodily or facially at your own distance around their reaction to your control.
Its provocing a reaction right in the middle of the bridge, instead of over your side or theirs ,as per usual.
