What is everyone's preference on using vinyl or urethane slugs.My driller has been telling me for a awhile i have very dry skin and should consider a vinyl slug. Well i have been fighting it and fighting it for awhile now and decided tonight to try it out. I didn't get a chance to bowl with it but it seems like i may like it. Didn't feel like i had to put a death grip on it to hold it. What does most everyone here use and what are some pros and cons. The problem i was having with the urethanes is that i just simply loose the ball sometime. Any replies are appreciated.
