There are a lot of low time pilots and not a lot of skilled mechanics so you have a good chance of spending most of your time in the hangar
I don't know how the situation is in UK but we hire pilots straight from flight school as loadmasters. Meaning that they assist the PIC and get some stick time during ferry flights etc. Normally it takes around 3 years until they reach the 500 hrs PIC time that we require to let them loose on their own. Since our main activity is utility work off airports we think that this is a good way of learning the trade.
Our "problem" is that our pilots leave the company for offshore or air ambulance work as soon as they reach 2000 hrs in command. So therefore we have to recruit low time pilots like you Zeus2011 and run what I like to call it, an "Advanced Flight Academy".
So if I could choose between a pilot and a mechanic I would take the mechanic any day
But a pilot/mechanic combination may be worth his weight in gold under certain circumstances. Especially for us who often operate at very remote locations. But to be useful you would need a B1 or better a B1/B2 licence.
