I have no tweed, and I really need some. I've scoured eBay to try and find a cheap starter piece, but I've never found any SC that was side vented....all the vintage pieces are single vent. I don't really like the way single vents fit me, all of my SC's and suit jackets are side vents. NORE - I'm interested to hear more about the 2 RL jackets you posted teasers of. And that goes for anyone else that has some nice side vented tweed pieces.
