Being new and in the learning phase I’ll guess this is all pretty confusing so let me help you down the rabbit hole of madness.
1. Hydros is an excellent b/c, well made fairly modular and very popular world wide.
1.a. If you haven’t used it and you can trade it in for the S tec that is a great option.
2. Halcyon makes great stuff for conventional bp/w, well thought out and made, so does Diverite, Zeagle, Hollis, HOG, Deep 6 (if in stock) and sub gravity.
3. I really want to try the S tec but pretty costly but it looks like a step forward in design, what I don’t know is if that step really solves anything.
4. Look at Sub Gravity, it’s not well known but a few people here have tried it, it’s about 1/2 the cost of the S tec and offers more wing options.
there are manny ways to skin the catfish, so many people lock in on one thing and feel there is no reason to try new stuff, I personally can’t fathom such thought processes
if you can’t return the Hydros take a serious look at other alternatives after racking up a bunch of dives in it, use the hell out of it and sell it if you feel the need for more
5. Avoid dogma!
