Patrick set me up with mine. I'm tall, but I just put my Stealth Tec on my 5'3" wife and it looks just fine. She can easily reach the dump and the bladder is over her low back and extends a bit lower. If she were 5', I concede, this would be too tall, not owing to the plates but the bladder would be too low over her butt and would require some weird weighting, and might be harder to reach the dump. In that case, the classic, or maybe the rec (don't know the height) would be better.
OP, sorry to hijack, but at least we're bumping your ad to the top
