Phil,
As much as I take the piss and think your cock is smaller than a hamster's, you have my respect for the fact that (even with help) you attemped this side of things . However, for the sake of pressing a few buttons, why not tweek it for the mid-range a/f? .

It is good to see Mark, Simon and Karl taking the time to help you too, so I hope your appreciation will show in true style .
