Not really in my case. The stiffer/longer Quattros would yield more propulsion IF I could drive them hard enough. However, I can't/don't, as that leads to early fatigue/cramping. I'm good for about half an hour with Quattros. (If I were diving every week, I'm sure my tune would be different.)I'm guessing the trade-off [to shorter] is a little less propulsion?
On the flip side, back kicks are more effective for me with the taller sidewall of the Switch.
