After watching the first Sigel instructional here's my review:
Good camera angles and good drills stressed for trying to gain a straight stroke.Mike and Trudeau really stress obtaining that straight stroke before moving on to the next two DVD's.They explain things really well.The drills are progressively harder and really test you for a straight stroke.They really stress the importance of stroking through the cue ball.
I think that's really good advice because if you don't have a straight repeatable stroke,you will undoubtingly stall somewhere on the road to mediocrity .They make that fact really clear.
This DVD is especially good for the novice as many instructional DVD's quickly skim through the basics, (which are of utmost importance) and get on to more advanced stuff too quickly.Sigel and Trudeau spend loads of time explaining the basics.This first DVD will leave the intermediate or advanced pool player wanting(or pissed

), especially if they allready have their fundamentals down.
As far as stroke goes, they don't really explain too much (in detail) troubleshooting (on how to correct things) if you are pulling or pushing your shots left or right of center.They also don't mention anything about possible dominant eye sight problems and (see Joe Tucker website) remedies.This is where live instruction with a certified instructor cannnot be replaced with a DVD instructional.
All and all it's one of the better instructionals I've seen, for the BEGINNER to learn the basics.
