Who has experience with a backstaytensioner on a Sun Odyssey 32? And which system are you using for it? Does it help te improve the sailing properties? And is the boat strong enough to absorb high tension of the backstay?

I don't have experience with your boat model specifically, but I have sailed on many boats that use various forms of backstay adjustment. Overall they are very useful, allowing you to tension your forestay and flatten your main by bending the mast. Exactly how effective they are really depends on your rig design. On masthead boats it is going to give you good control of forestay tension but will also induce mast bend, particularly if used in conjunction with a baby stay. On frac boats they are going to work even better for mast bend. If your boat has swept spreaders then your upper shrouds are going to have the most effect on forestay tension, and how much you can bend your mast depends on how stiff your mast extrusion is.
In terms of adjustment methods, the simplest type is the split backstay with a purchase system that draws the 2 backstays together to increase tension. They are inexpensive, and quick to adjust. Larger boats will tend to have hydraulic adjusters that give you much more power. They are quick to adjust, but are much more expensive and require more maintenance. There are also screw type adjusters where you just turn a wheel on the backstay. They are less convenient and slow to adjust. You will typically find those on cruising boats that don't adjust their backstays often.
Whichever form of adjuster you go with your boat should be able to handle the higher loads, as long as you don't go crazy with an oversized hydraulic adjuster.
