Very interesting Peter but there are a couple of problems...

I love classic sidecars and although it would be superb to see them on the mountain course again, I don't think you'd get a full enough grid and there wouldn't be enough time to practice them unless mornings were brought back and/or evening sessions started at 5pm (both things would make me very happy by the way). Unfortunately the Athol St mob would dump all over that idea...

You wouldn't be able to run the Senior classic at the TT again because of practice issues. They wouldn't be considered fast enough to run with the regular TT stuff and without extra sessions, this couldn't work.

I think we're both on the same page with the idea of a post-classic race at the Manx but not how it fits the programme. The trouble with the newcomer's race is you can't tell how many entries you'll get. The last two years have been pretty sparse, so my suggestion for race week would be:

Monday AM: Lightweight/Ultra Lightweight (see my earlier post about the 250 field)
Monday PM: Senior Classic

Wednesday AM: Junior/Lightweight Classic
Wednesday PM: Junior

Friday AM: Post Classic (TZ250/350/750, RG500, RS500, Tridents Rocket 3s, P&M, Jotas etc)
Friday PM: Senior

This would give a 50/50 split between old & modern and really appeal to those who love true race machinery.
