I'm putting together a secondary system that I'll be using for stitching and other misc renderings. Most of the hardware is ex-server equipment. I don't even know exactly what I'm getting yet, but the CPU is a recent quad core Intel. It's a mixed batch of systems and I'll choose the best.
I will be purchasing a new hard drive. Will a faster drive like a 10k-15k RPM speed up the final output in PTgui? If there is no bottleneck there I will just get a standard 7200RPM.
Running PTgui with a 3.6ghz dual core doesn't seem to use much percentage. What factors will help speed up stitching and final save the most? I'm going for at least 4GB ram, maybe more. I tend to keep Photoshop and other programs open too.

I like to make my own stuff. I'm on my 3rd wood panohead prototype which is a cradle type that supports both landscape and regular with full rotation and cam selectable lock points.
So when I got to the nadir problem.. I used a monopod with some brackets that clamps level with my nodal point, and is supported on the other side by 2 collapsible legs taken from a free Dolica tripod I got on newegg.

I would show pics but it's all very ugly, but functional :p The legs must be masked out, but it captures the entire section of missing nadir. I place a coin under the nodal point while taking pics and use that for alignment.

I've experimented with flat rectangular stitches at 120mm. Using PTgui you will have no problems at all. The program handles multiple rows very well. Add plenty of overlap and you will get plenty of automated control points.
For your setup the Nodal Ninja 5 would probably work best. www.nodalninja.com/ It's a little stronger and made for longer lenses.

I'm really liking example shots around the web. I was going to buy the popular 8mm fisheye sigma, but then I would only use it for Panos.
I haven't seen any 360 Panos labeled with this lens. Anyone using it?
The angle of view is 102.4-63.8°.

I've been shooting 18mm-30mm. Taking more pictures isn't much of a problem since the programs do most of the work. I stitch 130-190 pictures often (bracketed). It can take quite awhile to process though.
The outcome is much different. The movement of the pano more resembles video with less warping.

Thanks.
I forget to check for dust before shooting, so that explains the confetti 
What problem with exposure do I have? I'm shooting 4 stops (HDR). I have a less processed version here: cashtube.ws/pano2 Shooting in direct sun I didn't have much range to choose from. Next time I'll choose a better time of day, like I said it was a test. I think I left the shaded areas dark during processing, but I kinda liked the look.
I'll work on sharpness on the next set. I'm going to re-shoot this one again after I get a technique down. My tripod was straddling a rock so I probably lost some sharpness with some slight wind movement. I need to make some hanging sandbags for my tripod legs; an old trick I came up with for night shots at the coast.

cashtube.ws/pano
One mile from my house I went to test new stuff so I expected this would be a scrap/learning project. Besides the shadow, I like it.
This is Prospect, OR "Avenue of Giant Boulders". It's located on the other side of the Mill Creek falls trail. I'm going to pano as much of So. Oregon as I can for a hobby site this summer.
