Upside,
I am by no means experienced when is comes to making judgements about what employers are exactly looking for, however I do know a couple of people of have been for jobs with quite a number of SE hours, like 2-3000, and not getting them!
From communication with these people it would appear the trend is that your man or woman with perhaps 1200 hrs TT including 300 multi, is a lot more attractive than a man or woman with 2-3000 hours on singles. So it might be worth cracking on with your 40 hours?
Just a thought, I would be interested to see what others think, as I may be talking out of my ass

.
Cheers.
