I love my Strange Targe n Charge. Since 90% of my kills are Grenade Launcher/Loch n Load kills the Tide Turner doesn't really appeal to me. I prefer the resistances+afterburn immunity.
I sway between Loose Cannon/Scottish Resistance/Ullapool Caber and Loose Cannon/Chargin' Targe/Bottle when I'm playing Demoman seriously, it all depends on my mood (and how many Pyros or Sentries the other team has)
I tried Tide Turner/Persian Persuader (first with the BASE Jumper, which saved my ass once because of the comical hot air balloon effect, then the Bootlegger) the other day while goofing around, managed to be a top scorer a hilariously large number of times and got a 3-kill-combo at least twice
