Easel doesn’t handle thin fonts well. 
It seems that for thin cursive fonts you want to use a v-bit for best results.
@JarradTrudel did a nice sign using Aspire. Though I am sure VCarve would have done just as well.
Currently Easel doesn’t support v-bits (thought I am sure it will eventually)
Thought @Rusty did a post on how to set up easel to use v-bit in place of a standard bit.
