Drilled my Zenith Solid 40x4.75x40 and left it at box finish.
The idea was to have a tank to handle high volumes of oil but with more pop down lane than my Prism Solid (which I laid out too strong) so that I could hopefully keep it in my hands for a couple of games.
My first experience with the Zenith was actually for a ball video (see below). The Zenith comes out of the box at 1000 grit and definitely reads the lane very early, picks up a lot in the mids but has enough energy down lane to finish down the lane on heavier volumes of oil. Using my standard ball speed and hand position I was a little deeper than I wanted to be on our house pattern but had no problem mixing the pins. As with my Prism Solid, moving a little right of the third arrow and amping up my speed gave me my best look on this pattern. The big difference between those 2 balls was that once I softened up, added spin and got into 4th arrow, the Zenith pushed a little further down the lane with more energy on the back end giving me a surprisingly good shot from inside.
The Zenith really saved us in our challenge league on 44' Titanium. This pattern played REALLY slick this past Tuesday with my Warp Hybrid, Authority and Kingpin Gold still through the break point playing right of 3 arrow in game 3. I managed to keep the Zenith in my hands through the end of our 4th game (5 man teams, 1 team per pair) and was pleasantly surprised to see my best game to be game 4.
Compared to other balls in my bag, the Zenith fits happily between the Prism and Warp Solids. The Prism is great on shorter and flatter patterns where the back ends are strong but doesn't want to make the corner when I try to open my angles. I have found the Warp to be a bit tough to read as it has even more back end motion but is a tough ball to control as it can be giddy when seeing the friction early. As a rev/speed balanced bowler, the Zenith takes the tank slot in my tournament as it is the most versatile and most consistent of Brunswick's 3 most recent asymmetrical solids.
Compared to other strong balls in my bag, it is a step earlier than my Zing Solid and another step more ball than my Omni (sorry B fans, but it has replaced my Vapor Solid).
I recommend the Zenith for bowlers of medium to higher ball speed and those with spinnier ball rolls as a great option for slick lanes.
