modern wetsuits - not made for longboarders

I have a problem with winter suits 6/5 or 6/4.
Basically all suits I have tried are very quickly destroyed below the knees, due to my longboard kneepaddling. Most brands I have used through the years, O´neill Rip Curl Vissla etc. only have knee patches made for shortboard and not for longboard knots below the knee.
I don´t know if any of you guys have the same problem? I am 190/6.2 tall and perhaps I have long thighs which pulls the suit up?
