i think the greater problem of the griffin is that its response to turning is poor ( along with its huge size ). ... some ships have that problem, mostly light fighters... - that means they either do ( or appear to ) roll first before they turn. ( BHG sea serpent is a good example for that )
an example for a quick response is the hammerhead, which turns AND rolls at the same time, making it appear to be more agile than the griffin, which - by numbers should turn faster.
the only opponent i ever beat in a griffin was a barghest ... and thats pretty poor. ... i was even outturned by a manta VHF when i was flying a griffin. other than that problem, the griffin is quite fine.
