Here are two wyes ,one using the 481 mm radius curves all the way except on the #6s, and the other splitting between the 481 and 718mm. This really depends on how much space you have, and you could even use smaller radius curves, just keep them matched and symmetrical. The small pieces on the straight are the 29mm 20091B parts. You can, of course, mix/match the order of the straights, or use other combinations.
