I think the pattern is a significant improvement on last years. Length, oil and buff have all been increased. I dont think the oil durability will be a problem. Yes it may dry out a little with some traffic but there is plenty in the middle to last all day (even for the swingers).
The pattern does look a little easy, I expect the winner to avg 235 with maybe 2-3 x 300's during the tournament. At the end of the day though, everyone has a shot, and a chance at winning the tournament if your right/left handed or if you have revs or no revs.
