**Update**
As others have mentioned before, it's not the bike that is twitchy, it's the rider--they're absolutely right! The weekend after I posted this tread I spent a good three hours at the local bike shop that sells recumbent bikes trying out both the Giro 20 and 26. After that amount of time switching back and forth between both bikes I was equally comfortable riding both however the Giro 20 just felt right to me which is what I ended up purchasing. Since then I've been riding the bike so much that I do not miss the upright bike I just recently sold at all. The Giro 20 is simply a blast to ride and very stable at even high speeds!
Thank you all for your help!
