Agreed. Carry will be an issue. The longer you stick with it the worse your carry will be (typically).
When the night starts backends are clean and the ball is probably clean. Carry can be decent. However, every shot carries oil down lane and also adds oil to the coverstock, which is not really going to soak up oil like resin, so it will stop reading friction as well as it did earlier.
If it were legal to spray a good ball cleaner every game to clean excess oil off the cover carry would be somewhat better, but you'd still fight your own carry-down.
I have a friend who is high revs with good speed and he does better than most with my U-Motion that I barely use.
A nice strategy to use if someone else is using urethane against you is to move just outside of their line so their carry-down creates hold area for you.
