If I’m honest renton I think you seem like you could be one of a few people who could benefit from going and having a bike fit done, especially as it’s your first road bike. Based on your previous bikes you seem to be a very funny shape and like an unusual riding position.
I would say it’s time to go and see a professional and get some proper advice about how to make that bike fit you. It will cost you an extra £50 or so, plus some for a stem, but compare that to however many years sat in the wrong position, being uncomfortable and swapping and changing stems and bars every few months and it works out as good value.
Edit: £30! Well done. In which case you should definitely be able to find £50 for a bike fit.
