this is very true,when my friends & i played in the 70s & 80s we did not have a weight limit,but i image we played around 7-8 grams some figs weight was far less(wr,rb,cb,s)so on but since i have returned to the hobby 4.0 is the tabu,to me this is still very light,heavier does not mean stronger or faster but the weight takes the shock of the board vibration out of the base giving it a smoother run,this is what good tweakers are able to do without using weight,so why is there a limit?i'v only been back for 7 months,whats realy going on?whos afraid,& why?
