Replying to Does detuning ruin skis?

Hey y'all. My main question here is if detuning skis actually helps protect them from edge cracks while hitting rails.

Here is the context / reason for this post:

I have a new pair of unmounted 183 Vishnu wets that I got as a well overdue upgrade of skis. I was skiing on some old Volkl 163 length park skis. (I'm 5'11 so these are tiny for me). My dad was asking if he could sell the old skis to his work friend for their son. He changed his mind when he saw the edges and said they are junk. For those skis I did go overkill on the detune and rounded off the edges. He called me crazy for doing such a thing and was pretty much horrified at the idea of me doing something similar to my brand new skis. I was explaining that from what I've heard and read that detuning helps protect from edge cracks, and from my experience feels much better on rails. He said there was no use of detuning since cracking your edge will happen either way. He described it as beating my skis with a metal pipe, which would lead to a crack in both scenarios. He also pulled out the "I've worked in ski shops for half my life" card, and I would like to listen to his advice, but have heard conflicting views. When I bought the skis, Emmet put a card in the package saying to detune immediately. Although my dad thinks that having no effective edge is a terrible idea and that the advice I'm hearing is from west coast skiers. (We are from Maine). I am aware that these are park skis not meant to be all mountain. I will be mostly skiing at a small area near my school, so I figured these would work great for that scenario. And this post is not meant to clown on my dad, please don't turn it into that, but to get a better understanding of the topic.

So what I'm looking for is some advice on what to do with brand new skis. I planned on running them a week or so before detuning them anyways. Do y'all like somewhat sharp edges on your park skis? Or should I bootleg replicate the bdog edgeless? I haven't had a real problem skiing with my other skis with rounded edges underfoot, but I also haven't skied on sharp edges for maybe four years.

Sorry for the long read. Would like to hear your take and or advice.

Thanks.
