Node locked license with dongle?

I have one NX license and am the only one that uses it.  NX is currently set up to use a floating license; however, I recently encountered an issue with it (while upgrading) that required almost 4 hours with tech support to resolve.  I'm now wondering whether a node locked license with a dongle would be a better (less error prone) way to go, especially since I'm the only one that uses NX.  I believe that is still an option. Any thoughts?  The issue still isn't fully resolved, but if this is a viable option, I may bring it up with my VAR. 

Thanks for any feedback on this!
