I too was looking at the Bertini X4 pram as it did everything i wanted & i loved the large wheels on it. When DH looked at it he commented on how bulky they seemed & that the steering might become an issue. I still loved it though.

We ended up going with the new Valco Rebel I.Q that has just come out on the market. The wheels are solid rubber intsead of pneumatic so no risk of punctures. The front whells are slightly smaller than the back wheels but still a good size. It was also very easy to steer & reasonably light too.

I'm also in a country town & did a lot of research on prams. Good luck with your search.
