Practice Drills

I did some searching around for practice drills and found a number of videos with some good ideas.  Then I found the one below which encompasses all the drills I found. :)  I only got a chance to try the first drill mentioned today - but it was a real pain.  It was at the end of the day and I hadn't been shooting too well anyway.  *sigh*  I will be trying these over the next week and see how it goes.
