5miles,
I don't think having more STARS is a huge problem personally. It's mainly areas like Midlands Group airfields and NM's etc that have such far out descent sectorisation restrictions. The LL's and KK's and alike all have stars that include all restrictions, because they are not forced down so early relative to where they would like economically to start descent.
Don't get me wrong, I understand that overall system capacity is better for the restrictions you have, and I support that.
When I come through 19 and the SC is working his balls off, I believe the last thing he really needs is a string of routing instructions to relay, and hear read back - it makes keeping on top of a difficult and tight tactical situation so much more difficult. Recognising that, extended STARS to those particular airfields must be a solution. I pushed heavily for it back in LATCC days, but LATCC Ops in those days didn't want the extra workload involved with extra amendments etc.
As for flight plans, routings should be right - I know all my companies are, as they get very direct feedback if they deviate from the RAD rest assured - I phone straight away and get them to sort it! IFPS should reject any plan that doesn't conform to the RAD and require operators to re-file accordingly.
Hope to catch you for a coffee sometime when I'm next visiting!
