Interesting comment. And, why is that?
Because it has become the most recommended Sidemount fin in existence
It is light, neutrally buoyant, versatile, flexible, the only disadvantage is it's length (but: length equals power).
It can take strong current, but is also extremely accurate with small movements.
It is also hard to damage for a fin not made from a single piece of heavy and inflexible rubber (that dives like a much too short plank strapped to the foot).
Also: It is one of the oldest and most available types on the market.
If you loose one or simply travel without your own, you will find some old model at most dive shops in the world, discolored form being a wall ornament for years perhaps, but you will find one most of the time.
I am intrigued by the fondness for Force Fins.
Used them, loved them, got rid of them
If you want to save a few bucks, try finding the 'Adjustable ForceFin' variant.
Imho ForceFins are not ideal when used with a sidemount config. They work, but they loose their main advantage.
Because they offer most propulsion not on the kick, but when flipping back into the original position, they simply need a Backmount configuration for maximum effectiveness, to work against the out-off-balance tank position.
In Sidemount they are just fins like every other fin, only short, wobbly and not very powerful.
They do not work well with drysuit configs. Pulling floaty feet downwards is a real pain with them.
The Exellerating ForceFin is the only variant that works for everyone in sidemount, but it is used like a normal tec rubber fin most of the time and way to expensive for that.
