Here are some comparisons between SCT (PinPoint) and ST (Wedge) tires, both the same Z3 compound from ProLine, very similar in outer dimensions with the OD of the SCT tire at about 109mm and the OD of the ST tire around 105mm:



Both tires actually weigh the same without foams at 59g each!


The closed cell foams weigh twice as much, 16g vs only 8g for open cell foams:


The wheels were actually comparable in weight at 30g for SCT and 28g for ST:


There are many spoke wheel designs available for SCT, but I opted for heavier dish style wheels to stay in the spirit of the class
