For those that might know me... I LOVE the Vibe core and haven't had a bad Vibe / Viral matchup... it is one of those cores that matches up for all styles of bowlers. Even with the modified Vibe core in the Burgundy & Blue Hammer, they provide a consistent ball motion that is reads all 3 parts of the lane effectively.
I took my Viral Solid down to 2000 to be my most hooking Vibe/Viral to date... and the Burgundy is second to that one... If you have a higher rev rate or high ball speed... you NEED the Burgundy Hammer... the react-a-thane coverstock blends out the over/under motion, yet still offers a nice continuation backend motion. This ball is very underrated for many flatter tournament or over/under house patterns. It blends out the pattern. This is my favorite piece with the Vibe core due to the smooth reaction that I see with this ball for a variety of lane patterns that I see in tournaments.
Hope this helps and if you have any questions, please let me know!
