Track 400a layouts. To get more effect on reaction drill the thumb hole deeper, being sure to keep the static weights legal. For starters, this marks the first time that Track has released a ball in the 400 series. The layout that I choose for this ball was drilling #4 and drilling #3 on track drill sheet (made adjustments according to my PAP with relation to the wording on the sheet) My PAP 3 ¾ over ½ down 17. 055 Ball review: The 400A SE looks unique and will definitely be something you will notice when someone throws it.

The 400a is a high differential ball so it has a high flare potential. 5 mph ball speed. Re: Need an advice (Track 400A layout) by MegaMav » Sun Dec 22, 2013 6:11 pm Pavel wrote: Well! In this case there is no point to have a such hole lower than 2’’. The 400A Special Edition is the newest symmetrical cored release from Track. We improved upon the performance and looks by using the highest grade resin available in our new Luxury MA cover. I went with the 2" down bal hole in my suggestion to get the ball to read the lane earlier without increasing the flare which will already be considered high flaring. When we developed the 400A Special Edition, we wanted to create something truly special. 58 Diff: 0. The bigger hole - the more influence. You might recognize the DNA Core from the earlier released Track 300C Solid. This Core in the 400A assists the ball by getting it rolling down the lane while storing the energy for the backend. There are several features about this new release that help make it unique. -- JohnP Pavel Member Posts: 66 Joined: Thu Jun 20, 2013 . For details on our standard test layouts, please click here.
