Hi Todd, Our systems do a lot of deletions and it does cause problems.
Your best bet is to bring GCSeconds low and run repair religiously. The issue you can run into though is repair overloading your servers when your data load gets high, repair falling over and related problems. IMHO the need to run repair really needs to be addressed urgently. I proposed an alternative approach here https://issues.apache.org/jira/browse/CASSANDRA-3620 so vote it up if you share problems!
