I am thinking about trying one of these. Our lanes are spotty and if I try to play up the track with reactives, they snap way too hard on the backend but don't want to recover from deep inside. If I go with an aggressive reactive or particle from the inside, there is not enough oil in the heads to hold it long enough to make the break point.

 I was thinking I could polish one of these up and play up the track because it might not have the "snap" on the backend like the pearl reactives.

Just call me Darreyl, it's much easier to say!

Depending on your speed and other factors, you should be able to drill it up to play straighter up the track with it.  I wouldn't drill it with the pin too strong because the ball will flare...just drill it with the pin next to or under the ring finger and then play with the shell to get lined up where you want to be.

The other thing...if you haven't used urethane in a while you will have to remember that they are far more sensitive to oil in the back end.  They also carry the oil down more dramatically then their reactive and particle buddies.  I have had many occasions where I was using urethane and actually carried down the oil on my line and had to move my feet right.
