Questions for National Geographic TOPO! Users

I have two questions:<br><br>First: How many of the National Geographic TOPO! Users here are using the version 3.x of TOPO! and if so how do you like it? The version is available here as a free upgrade: maps.nationalgeographic.com/topo/instruc...?state=yes#topostate

I have mixed feelings about it. So far I've found the UI less intuitive, bloated and a bit slower. I'm almost considering uninstalling 3.3.4 and installing the latest 2.x version


My second question is: If I purchase TOPO! Backroads Explorer (which includes 1:100k scale topos for the entire US) and I already own TOPO! State series for a state, will Backroads Explorer integrate with the State series to allow me to see the latest road information on 1:24k scale maps?
