All the parts you mention are made to work with magura! and will not damage the brake, water will over time damage the insides of the brake.
The new evo brake from magura is made with trials use in mind, better fittings like 4 bolt clamps yet they still bleed with blood. The germans know what they are doing, or they would sell the brake with a bottle of evion.
water bleed = damage to brake internally , more time to bleed as it fades over time. not covered by magura warranty
royal blood = made for the brake only needs bleeding if damage to the hose. if brake leaks full 5 year warranty.
At the end of the day its down to each rider to make there minds up, I'm not fighting to say it does not work because it clearly does and so many people are happy, i just don't get the effort having to bleed the brake every 3 months and to make sure you don't forget the anti freeze in the winter i can get my bike from the garage sun, rain or freeze and know the brakes will work from the start.
