As a matter of fact, I wonder why you're so afraid of this dropping. It's
usual method of auto-regulation e.g. for tcp. You've written latency isn't
so much problem, then slightly overloading ISP's queue you'll always get full
bandwidth, you've payed for. You didn't write what kind of traffic you service,
but I doubt you can get rid of dropping everywhere: on your HTB etc. queues
or on incoming traffic.

Did you try to dig at this very nice HTB page?:
