I played pretty much the same list at the last tourney at Warhammer World.

I won 3, lost 2 very closely and got smashed in 3 games. Whilst individually your guys can hit hard, it's the lack of numbers that really hurt at the end of the day. I didn't make a single bottle roll all day (my usual luck).

What I found was anyone with a decent amount of shooting will just sit on the back edge of their deployment and try to bag 1 or 2 of your knights as you try to close.

If you can I'd try a couple of practice games against a few different armies, especially shooty armies like dwarves. I'd definately get the steel lined cloak on someone to boost their save. I'd drop the banner myself. I only found it useful in herding peasants in some of my practice games I played with my first list I put together.

I'm going myself again this year, but I've defected to Dark Elves. Never played them before and thought I try something new this year.
