Sometimes the trick to finding the right answers is to first ask the right questions.
Question 1: all spells require the raising, programming and sending of energy, how do the various components that you can use for spellcraft fit into the process? how do the actions you take and the components you use combine with the energy raising/programming/sending process?
Question 2: picking components is easy, but once you have them, how do you decide what to do with them?
Question 3: Once the ritual of the spell is done, what do you do with the components?
Question 4: if spells can be cast without the use of physical item, why include them in the first place?
