If you need to put in 10 chips for your blinds, then counting out ten chips (especially if a person hasn't figured how to put them in stacks of 5 and count quickly) can add to the time. And if you've got a million little chips, every raise will require counting. I like less chips, speeds things up, makes it wasy to count everyone's stack quickly and helps your calculaltions.
We start out T2500 with only 26 chips, blinds start at 25/50
