Dennis, What balls do you already have that work well on the pba and sport shots?
I think the Ultra might have too much back end for many of the shots at the Nats and other tournaments.
The Fresh, National shot will require a heavy oil ball with 1000 or 2000 dull surface played up the 7 or 8 board out to 5 or 6 until the shot opens up, then a shiny surface in a similar ball will probably get you through. If you bowl on a second or third squad singles and doubles, the Ultra might come in handy though. Your Shift will also play well from straighter angles.
is 2ft longer with a flatter 1 to 1 pattern with less oil than the national shot, similar to the US Open. If you get there early and bowl on fresh, you will have to be accurate and use a the same dull piece you use at the National team shot and Open up a shot from yourself from the second arrow, be ready for quick ball and line changes. The Ultra may be too jumpy off the break point on this one. The Shift might be more controlable.
The Bowlers Journal
is also 43 ft, but has less volume of oil than the BTM
, but is a 3 to 1 pattern, here the Ultra might be a good ball if you end up covering a bunch of boards.
I have heard that the Storm Sport Bowling Challenge is a short pattern, so bring your shift for that one.
