Keep in mind, that a snap switch has a purpose, and that Atlas now makes a 22" radius snap switch in addition to the 18" radius snap switch. They are much improved over what they used to be. I haven't used any since I built a Christmas garden layout for the kids in the mid 1980s. Back then they were junk.
If you are limited to a 4x8, you are pretty much limited to 22" radius as your widest curve, but you can still use Atlas #4 and #6 custom line switches, or PECO #5 and #6 switches, as an alternative to snap switches. But if you need to use a snap switch, it will work for you. The trick with sectional track is in the way you lay the track and fasten it. it's much too easy to misalign the track and create derailment opportunities.
