When it comes to striking Silva can definetly show his striking without any disadvantages beside power. The weight difference wouldnt be a factor in pure striking unless he is put on the cage or using MT clinch.
The weight difference has been nullified many times in K1 when watching elite 200lb guys beat elite 250lb+ guys. Look at Tyson in his HW prime, the guy was small but his speed was devastating.
