BJ Penn with a spear against Frank Mir with a switchblade.
BJ would need to utilise the length of the spear and keep Mir at a distance, giving quick jabs and thrusts. Mir would need to close the distance and use his bigger size to smother BJ and be able to make use of the switch blade. BJ must be careful not to let Mir grab the spear and hence be able to close the distance on him. If taken down BJ must just get up asap and not try and engage in a grappling match, the spear is of no use there. For me it's all about who can work the distance most effectively.
