BTLOS 30mm wheels for pure climbing?

[shinomaster]

I noticed they have free shipping and the weight of these is pretty crazy. I'v come to realize I mostly climb (it's very hilly in PDX) and don't do any fast pacelines any more and at 50 years old I am not getting any faster. What I do enjoy is having a light bike and climbing. I weigh around 155 depending on the years. I should weigh 144 and am hoping to bet back down to that soon when I switch from solid foods to lettuce and Soilent (JK). Has anyone been using the 30mm premium wheels for just a climbing bike? Are they any less durable than 35 or 40mm? Thanks!

Also these are rim brake as I have become an old retro grouch evidently.
