I just can't imagine needing 100oz of water for a half-marathon. Maybe I'm the camel or something, but on my training runs, I didn't drink at all. (I did train during the late summer in the early morning, so the temps were close to ideal.) I couldn't see needing more than a belt even if the weather weren't that great.
Seeing how this is my first half-marathon, I am not quite sure what my intake need will be, especially in May in Georgia, where it is often humid early in the year. I was also considering the larger size for future races, as I would rather make one purchase (if really needed) versus making 2 or more.
Thanks for the reply.

I didn't like the hydration packs for marathons because of the continuous repetitive motions of the pack on my back. I tried cinching it closer to my body to keep it from moving too much but it became uncomfortable. The waist packs fared better in my experience. I've dealt with chafed nips, lost toe nails, etc, but the discomfort of the hydration packs was something else entirely. Nothing beats unencumbered running. I can tolerate it on trail running and mountain biking, probably because of the constant shifting. I cannot stand them on century rides on a road bike.
Your experience may differ from mine.
What you have further elaborated on, is a concern of mine with the backpack. I like the handheld water bottle, although using it makes it a little harder to feed myself with gels or some other small food item while on the move. I like my current hydration belt but, the two bottles only hold 18 oz collectively which, I am not sure if that amount it going to be adequate for the upcoming race, not to mention future ones. With the hydration belt, my hands are free to use gels and what not. If a backpack will afford me the same opportunity while at the same time not being a bother to me on my back etc., it is definitely something I think I should consider.

I probably wouldn't because I wouldn't want it bouncing around on my back. What you probably ought to do is find out how much water you're going to need to complete the race then decide whether you need to carry extra water.
Camelbaks are nice though and I think they still make the one that goes around your waist if you need just a little extra.
There is some merit in your reply. It will be harder to gage, as I doubt my needs at the moment are going to be the same come race day, with the temperature changes as well as the mileage increase.
If I can get by with something less, I am all for that. I just don't want to be in need and not have it. Granted, the race isn't until May, which gives me time to seek first hand experience from seasoned users, as well as monitor my own running changes and usage along the way.

I have their 3L Antidote and it's quite nice. I've only used it for hiking not running, but it works very well and can hold itself open for drying. I also have a 2.5L Osprey Hydraulics LT. I like the Osprey a bit better. It has a magnetic clip for holding the hose in place, which is a great idea. The plastics feel more durable. I like the Antidote's bite valve more than the Osprey's however.
This is one of the Camelbak models I have been looking at online.
