Well, from my experience synthetics tend to hold the shot alot better, but you hafta watch out for the shot being burned out. Best advise i was ever given for bowling on synthetics, is " if you think you should move, you should have moved 2 frames ago " so if you throw a shot and it checks up early, on the next shot move a board or two and keep your break point the same. I bowl in a house on a scratch traveling tournament that uses synthetics, and last yr, i started out playing inside 3rd arrow out to 10, and by the 6th game of the day i was playing just inside 4th arrow out to 10. And this was across 6 different pairs of lanes. So the change wasnt that great. Now in Wood, the backends will be softer, but i notice that when the shot goes, you hafta move! I bowl 2 leagues in a house that uses wood lanes, and normally play 15-10. And can play that shot untill the track burns up, which is normally by second game, because everyone plays the track, which is up 2nd arrow. so i know by the second game that i hafta start moving, and i also watch out for carry down, cuz on wood carry down happens faster, that i notice. But the easiest thing i would do, is to take some of your weaker stuff, to your first night and practice going up 2nd arrow and see what your balls do. But u also take in mind the weather too, if its hot out, on wood the oil is going to burn up FAST!
