What works for you in Sparring/Fighting?

[DogTheBountyHunter]

One of the best things I have found is always keeping your eyes on the opponents gloves at all times +
mixing it up to be able to throw a lead right cross or left cross for southpaws followed by a jab.

It still amazes me how rarely this is done. When Pavlik fought Sergio Martinez only one time did he throw a lead right and it landed. Jack Lowe never mentioned to Kelly in the corner to try it more often.
Once you have a fighter used to the same rhythm it will be hard to land. Mixing a lead power shot will keep them off balance and help land the jab more effectively thus changing the fight or sparring session as they will have to watch for not only a lead jab but lead from both hands.
