Vortex 4000 w/ Kestrel 2700 vs. Vortex 4000 GB

[judders87]

Hey folks, I recently purchased a Vortex 4000 but was second guessing myself when I heard about the 4000 GB. I currently own a Kestrel 2700 but was wondering if it would be worth it to get the 4000 GB and not have to use the Kestrel or have future capabilities with pairing with an upgraded Kestrel. I mainly archery hunt with rifle being a secondary choice. Trying to decide if its worth the few extra hundred dollars. TIA
