I do as well.
If I let my humidity drop to what is 'recommended' my bps run into shedding problems. I tend to keep my humidity higher than 65% and try to bump it up to at least 80% when I see them going into shed. I've had over 100 bps and never had an issue. As long as you keep your temps correct they are fine. From what I've heard, problems like an RI that typically get blamed on too high humidity are actually caused by bacteria from dirty conditions or viruses passed from another animal. It's possible high humidity combined with low temps could weaken the animals immune system but I never heard of an actual case of a bp getting sick from high humidity. I don't know much about RIs though because I've never had to deal with one and I've been keeping my bps with high humidity for years.
I've found cocochip or reptichip hold humidity best. I still need to add water to it weekly to keep my humidity where I like it but it's still much better than any of the many other substrates I've tried. Plus it reduces odor and does not mold even if it gets a little too wet like a lot of others.
