Thank you, I have been checking the weights of the ones I'm looking at, very valid point.
My major concern is which would give me more stability while I'm wheeling it?
The 3 wheel strollers, look like they could be easily tipped, but I don't know if that's true or not?
The 4 wheel strollers, look like they would be a more stable platform.
Something that would help me stay more balanced as I'm walking?
Sort of like a shopping cart essentially.
But honestly, I don't know?

Maybe, the 3 wheel strollers are not as tipsy as they look?
