Great! the long tail cast on is also the basis for many other cast on's!
the German (aka german twist, norwegian twist, twist) cast on is a variation of the Long tail.. It make purl like bumps on front and back, and either side is perfect for the front.
don't like the bumps? do the cast on *reversed or do it backwards, (hold yarn in right hand, needle in left..)
you can see how to do a reversed cast on by watching this you tube video..
(the video shows alternating standard and reverse.. but its just as easy to every stitch reversed.) this would make 'move' the bumps to the wrong side.
There are other options, too, beyond long tail --
there are 40 + ways to cast on, and while i think LONG TAIL or a long tail variation are great (and i use this cast on 50% of time!) you do have options besides long tail
see a cast on tutorial starting here..
there are 4 parts, (and links to the next part at bottom of each page) Part 4 is a list of links to tutorials and videos (the best i could find..) and to a list of reference books
