This is a great question, but I cannot give you a definitive answer.
A handful of some of the so called best pvps and/or fertility reversal surgeons out there are doing quite a few things differently. The hemoclips part alone is one of them things.
There is some truth in the idea that many reversal surgeons don’t know exactly what they are going to do until they crack you open and take a look. We have seen some of that play out in real time on this site and we’ve seen it more than once.
We have seen some other very interesting post/s related to the hemoclips reversal topic. I won’t get into details, but I can tell you were to look if you send me a PM.
I can hear the reasoning on both sides of the fence. I’m not sure if any of them are absolutly right or absolutely wrong. I have never seen any long term data sitting side by side to form such an opinion. I can think of potential pros and cons either way.
I have heard considerably more stories from men that had more less a full clean up of both ends of the vas deferens, but that doesn’t mean a whole lot. If I had an opinion based on what I know about, I feel confident saying that I would have some sample bias.
Guys like me just watch the scene and try to make some sense out of some things, try to learn more about it wherever I can, and so on.
Bottom line - ask the reversal surgeon you are considering all the right questions beforehand. You might consider getting some input from several of them. From there, you are going to have to make a judgement call. You are going to have to go with your gut. You have to live with the outcome of your potential reversal - nobody else.
Hope that helps
