I agree with a lot of these choices (Gut Shot yes, Increasing Savagery no, going down to one Lash...uhh, no), and will adjust my deck accordingly when I can.
I ran Livewire Lash in my old BG infect deck. It was really useful. Besides the normal +4/+0, you could pump the equipped creature prior to combat and eliminate potential blockers.

Nice to see another of my decks get a mention here, even though 'only' a honorable one. (I thought 3rd time would be the charm, but no luck!)
I actually played my Big Red deck on FNM last week, with some slight changes to the sideboard and a minor change to the manabase (-3 mountain, +2 Evolving Wilds, +1 Forest for Ancient Grudge from the board) and went 3-1, losing against my personal nemesis who played... Dumdumdum... Shape Anew and went 3-0-1 with it. I only lost that match because I had answers to Shape anew, but he didn't have Shape Anew and killed me with a Restoration Angel ... Then when he did have the Shape Anew in game 3, I didn't have the answers of course. Anyway, if you want to try out a nice anti-aggro list, Big Red is something you should consider!
When I started writing this post, I was going to criticise the Séance deck. But as I wrote more about it, I kept spotting more interactions, until... yeah, that's just darn cool. I want to build that now.
