Problems with Omaha low hand???

Was amazed that my eldest son is ''scared'' of playing Omaha Hi/Lo, I love it, so here are the basics, in plain English...
For the LOW hand only in Omaha, forget about poker all together...poker hands are ignored, it is just the numbers we are looking at here.
A low hand consists of 5 cards (2 of yours plus three off the table, as is usual with Omaha), they must all be different numbers AND they must all be 8 or less.
So the nuts are A2345 and the worst is 45678.
Be wary about going in too heavy on the strength of A2**, this can lead to multiple split pots and you could end up losing money with a winning hand...remember with the low you are playing for half the pot and if this half is shared then you won't get a lot back!
