An established attack on a reduced round version of a cypher doesn't mean the cypher is weak. A cypher must be considered in it's entirety else you are cryptanalysing a different cypher. It is accepted practise to attack reduced rounds then build on those attacks, but to imply a cypher is weak because it's six round variant can be broken in only half of eternity is misleading. (the nine round attack requires so much known text and so many related keys, it would be more practicle to mount a brute force attack)
