Changing my block lead leg

I ran a double 100m at the weekend and ran the same time in both races. I decided to run an experiment for the second race and ditched the blocks and swapped my lead leg despite never having trained it before. I did it because, despite having trained the heck out of my start, I still can’t get it right. One observer once said to try the other lead leg in the block. So I think the obvious answer would be to continue with the opposite leg now and go back to basics. What do you think?
