I didn't see all the info in this Q&A's, so i can't put in any info. But, I think you are very wise in stepping back, after looking at pros and cons, that you found.
I did see a couple of people that had something implanted and had to have it taken back out, because it was not the .....you will really like this.......benefit as was told. I am NOT referring to what you are looking at, tho, since i missed those comments. Just in general......One Dr., a few years ago told me, sometimes their "cure" is worse that the problem.............So keep searching, to make sure you are making the best decision for yourself. granted, sometimes we just don't know, until we try it.........but, sometimes, the cons sound so bad, one may not want to even try it. I know, this is no help, just suggesting a little more research until if, and when, you feel more sure of which way to go.
