I know you're asking about umbrella strollers, and I hope you can find what you need. That said, I've seen others mention it and I just have to add my support to renting a City Mini stroller somewhere. We have a City Mini double, and I have no problem pushing it. I'm about 6'3". It is comfortable for the kids and DW and I can both push it easily. In fact, my SiL and BiL like it so much they got a City Mini single and he's about my height also.
One word of warning... no matter what stroller you get, be careful about hanging big bags or bags with long handles from the back of the stroller with stroller hooks. I have to keep reminding DW that even though it might be fine for her, I have a longer stride and they are shin busters for me.
City Minis are *way* more than I am willing to spend to buy, and since we are going to Disneyland, the rental thing is not so much an option.
We are careful about hanging things on the stroller because of the tip factor. One of the nice things about the Ignite is that it has a good sized basket.
