I got my Reactions in 2013/2014 and while I haven't abused them, I don't baby them either. The only thing I would recommend is perhaps jump from the boat while holding the fins and put them on in the water, unless doing a dive that requires a negative entry.Hi Zef,
This is an interesting post as my wife came to similar conclusions. For the last 17 years of diving she was using Cressi reaction, as they are light (good for travelling) and stiff (providing propulsion, when required). Very good for diving, she liked them a lot...
=> These Cressi reaction are, on the other side, the reason why we are now looking for other fins: While the first pair lasted for many years, the blades of this fins broke, when jumping from the Safari boat into the water (happened now two times within the last two years). It seems that they take now another material for the blades that is good for swimming, but it is just mechanically not sturdy enough...
(What regards me, I have Scubapro Jetfin at home and use Aqualung slingshot for travelling (o.k. but not outstanding fins, they have now reached the end of lifespan after many years and several times exchanging the rubber spanners (I am not shure I could get spares any more))...

It would not surprise me to learn that Cressi made a change to the material they make the Reactions from, but I have no knowledge of this.
One other recommendation is to perhaps try to figure out how your feet are hitting the water upon entry and perhaps adjusting your technique...for instance if your fins are entering the water tips first and the fins are breaking, then try to do your giant stride entry so that your heels hit the water first, or tips firts if you currently enter with heels first and the fins are breaking.
Good luck.
