Re: rounded off bolt head
Centre punch the head then drill it off.
Conventional wisdom says to know your limits. To know your limits you need to find them first. Finding your limits generally involves getting in over your head and hoping you live long enough to benefit from the experience. That's the fun part.

Re: rounded off bolt head
Also as it's the last bolt it may also help to support the weight as this will also put load on the bolt which will make it tighter/harder to move. Get some plus gas penatron anything like that. What size head is it could you go for an imperial size? or dremmel some flats on it is a possibility.
