Hi, just thought I would jump in and ask the question what is the difference between the strider 4 and the strider DLX?

I have worked out that the DLX takes the capsual/bassinet/recline seat while the 4 just has the bassinet/recline seat - but are there any other differences esp ones that make one more user friendly over the other. It seems from the web that there might be a bit of difference in the wheels, but I'm not really sure.

Any advice or comments?
Thanks
FG
