For pretty much all my two seasons playing T11 ive used normal tackling and have only picked up 2 or 3 red cards & 20+ yellows in that time...i don't know if ive been lucky or not but it seems to work for me...

I've also had my share of strange results but ive just put it down to the imperfections of the game / game engine...

I'll also start soft tackling lesser opponents and see if it makes any difference...ty for the tip ...
