Stroller Help OVERWHELMED!

So I have points to use from my credit card and I thought it would be great to use them on a stroller..... So with that I can only buy from BestBuy.ca... I plan on having two children close together so I was looking at the multiple child strollers. I also go to the dog park and ride horses so I need one with the three wheels for "off-roading". I was leaning towards the Phil&Teds but they have so many options and I would love it if someone could simplify them for me. They have the Sport inline, sport v5 (which I'm not sure what the difference is) and the dot. Anyone able to help a girl out!?
