MikeeB, I'll try not to reiterate what's been said above, but, as you asked specifically for views from people who tried aeros with low hours, here are mine. Like you, I was motivated to learn to fly at least in part by a desire to fly aerobatics. I chose to learn on an aircraft with some aerobatic capability, and as luck would have it my principal instructor was and is an aeros nut, so there was a fair smattering of aerobatics as we went through the course. As mentioned above, the RAF throws in aeros early in its basic flight training, so there's really no mimimum hours requirement, and no reason why a PPL with circa 60 hours shouldn't try something like the AOPA course, which usually involves about 10 hours of aeros and associated training. I would be disinclined to take seriously the suggestion that you need more hours before you try aerobatics.
PS: I see that you are Yorkshire: I gather than Sherburn offers a really good rate on its Cap 10.
