The Cherry vibe is going to flip harder on the back end compared to the Blue Vibe. The Blue Vibe is more of a strong arc type reaction.
I don't own a Cherry but just bought a Blue vibe and it's money so far.
Almost any ball can work on a walled up house patterN. All bowling balls need dry boards to work properly. On your THS there's dry boards outside so it don't matter how much oil is in the middle of the lane. If you bounce the ball off the dry boards outside it's going to work just fine.
Now if your bowling on difficult patterns it's a completely different story. Most difficult patterns have the dry boards down lane and not outside. If the pattern is too heavy or too long the Vibes may skid past the break point. So it really depends on what kind of medium patterns your talking about.
Another thing that needs to be considered is coverstock adjustments. Even though the Vibes are considered light oil bowling balls in their box covers, they may be able to work on heavier/ longer oil with a duller cover adjustment.
Bowling balls today can be used on a wide amount of patterns/conditions with the right surface prep. This is why I usually buy two of the same ball and adjust the cover on one of them. You never know what kind of gem you will find with a cover change.
I hope this helps.
