I am designing a survey where respondents have to choose between options A and B. Instead of using a the typical check button, I wanted the respondents to use a slider to know the magnitude of their preferences. See the following example:

As you can see, the respondent selected 100: this means that he/she would always prefer option B . I have modified the scale for making impossible to select 50. I wonder if it would be possible to have something like the following image (or something similar to improve respondent comprehension).

Also, it would be also very nice to modify the scale for the respondent to be able to select all numbers except 50.
Any other ideas/suggestions are very welcome.
Thank you very much.
Daniel.
