At our RYA centre we have an early ribcraft rib, and it didn't fit in the shed. It is used every w/e and was deflated after use. It didn't seem to mind. Still going strong.
The hyperlon is very durable, and doesn't easily puncture, unless you drive a sharp spike into it. Ideally if you are having areas that are expoesd to greater wear, put wear patchs on them. We use these on a dive boat, so that when the tanks rub across the tubes they don't puncture.
Repairs are relatively easy, just use the right glue. They are much trickier if you blow a hole by the seam. Patches can tend to weaken if you deflate the tubes when patched, but if its a good repair it shouldn't matter.
Just make sure when you reinflate, you do so according to the manufacturers instructions, or you might pop a baffle.
