Right MNers, please tell me which is the best umbrella style pushchair to cope with "countryside"?

[champagnesupernova]

I have had a quinny buzz for going out on country walks and love that it comes with silly footmuff thing to keep warm in winter.
BUT I have been PLAGUED with punctures.
Also it's bloody heavy and getting to be a pita with DS as he's getting heavy (19 months and 27lbs )

Will a McLaren or similar cope with woods/rural paths?
TIA

Just to say - I just got a micralite from mothercare (or should I say placed order for one), using a code (from the discounts section) that apparently is only valid today Ff9 - and it got me 20% off - so only £132 - and just thought that was worth you knowing - it prob works on other stuff too - (if you want a different pram)....but like the lady that told me said - today only!
