Anyone using the V18, V15, or V35S Tubs / Racks? Opinions?

I'm curious about opinions on these shorter tubs. I put this post here, because I am curious about uses with different species, but please feel free to move this post to a more suitable location if needed.
I am personally interested in housing Kenyan sand boas (babies, juvies, adults), baby BPs, and possibly baby boas. Ideally, I'd like a rack / tubs that can work for different species as needed, but need opinions on the height of these tubs and how they work for people using hides, water bowls, etc.

These are 3.5" tall verses normal tubs that are around 5" or more tall.

I will post a link here to a rack that is using these tubs and has size references.

If you are using these tubs, I'd love your opinion on what species and ages / sizes of snakes you are using them for and what you like or don't like them for, etc.

If you are using a different style tubs / rack that has interchangable, taller, tubs, I'd love to hear about that also.

You can keep BP up until 500 grams in V18 basically allowing you to go from hatchling rack to adult rack and not have to transition several times. V35S are not suited for bigger BP.

Now you can use V18 for adult hognose and sand boa males and V35S for most adult females.

V15 are great for hatchling colubrids.

Thank you for your reply Deborah! I'm really considering going with the C-serpents 8 stack v35s rack..I think it may work well to grow out baby / juvie sand boas and keep adults in.. I have heard that you can house baby BCL and dwarf boas (like Nicaraguans) in the V18 tubs also, so that would be a bonus. I just wish that they had V15 and 18 tubs that were taller that would go with the standard v35...I'd rather have more height, but still interchangeable tubs.
