May I ask what kind of packs you are making?

I guess most guys buy the dewalt packs and tear them down because its cheaper. However, the cells used in the SPT's do not come with tabs so they have never seen solder or spot welding. The SPT's have several advantages over soldered packs. Anytime you add solder joints to your packs you introduce resistance so the SPT's have an advantage there. The one thing that the SPT's don't provide is an easy solution for balancing. However, I've been running my packs for almost a year and haven't noticed any issues.
The SPT's cost a little more, but for me, they are well worth the extra few bucks.
I've been using my packs for racing and I'm really surprised at the performance and run time I'm getting.
