All house shots are very dry outside 10 board. Agree that many seniors don't have the speed to play in this area. However most house shots have plenty of oil inside 10. If they don't seem to, it is more likely the length of the buff rather than the volume of oil. I use to see houses all the time that had plenty of oil, but only buffed about 35 feet. This is a killer for slow ball speed.
Bottom line, the THS is the closest thing to giving everyone something as long as the buff is at least 40 feet. Want dry move out. Want oil move in. Seniors with slower ball speed should be throwing shiny tame pearls, or even polished urethane, because the strong shelled balls will roll out for them even on a long buff.
