What they said.
I know where you are coming from, since last December I have hosted a tournament with friends from school each month. We started out with blinds increasing every 30 minutes and had blinds similar to you:
5/10
10/15
15/30
25/50
50/100....etc. etc.
But we found that the $5's were USELESS almost right away! No one was using them for anything but change because they are too low for any kind of bet or raise, and ultimately you end up with everyone having huge stacks of chips that they are not using.
I tried various things like removing the $10 chips so you were forced to use the $5's, but then people just started using the $25's instead; it created some great action but I still had a bunch of $5's not being used.
Now we start with stacks of $25's and $100's and the blinds start at 25/50 and increase from there. Less denoms work much better and are way less hassle so maybe give that a try at your next game and see how it pans out. Before I ordered good chips, I used my crappy composites thoroughly to test my denoms and quantities out in actual games so I knew what would work and what would not, I would suggest you try the same.
