Recreational paddlers generally aren't going to notice a difference at all. The issue is balancing losses from force vectors, the blades pushing and pulling towards/away from each other at the extremes of the stroke, and fluid dynamics where the larger blade has higher flat plate drag and wastes less energy as turbulence around the periphery. You can't have both without making special (wider pin spread) rigging for the boat which oddly hasn't been played around with much.....

Also of note, lightweight women through open weight men use the same blade area and very similar spread/inboard/outboard measurements. There hasn't been much interest in tailoring the rigging to athletes due to equipment expense and availability limitations, even at the Olympic level.

In Olympic sabre fencing men and women use the same timings which can mean that the women's bouts are actually a fair bit more interesting to watch sometimes because they're slower and more likely to make mistakes whereas the men's game is a finely tuned collision at high speed in the middle of the piste (i.e. unless you fence regularly you'll have no idea what's going on)
