What AT said about multis isnt entirely correct i think... if you need to force them, then dont use them... but whenever u write a line, think about it afterwords... if u can insert multis without changing the meaning of the line, then do it.. if it will affect the meaning of the line or flow, then dont... cos theres heaps of ways u can find rhyming synonyms that could work as multis. without chanigng the meaning...
