Difference Between Banishing Air Pentagram And Invoking Water Pentagram Options

What is the difference between the
LBRP using the banishing air pentagram and
LBIP using invoking water pentagram?

since the way to draw the banishing air pentagram and
the way to draw the invoking water pentagram is the same,

must be mercury last night making some funny aspect on my chart, i thought you were asking about diference between figures that are drawn for specific direction/element. in light of new day i see you are asking about ritual as whole. then as palindroem said... only when it comes to practise, i would use greater version for working with specific element, especially if it is invoking, it brings more focus and greater emphasis on element. as for lesser version, although it is ritual that should put you in tune with energy you are working with, you are one who has to know what is goal and purpose of working.
