Cthulhu - From "Call of" to "Trail of"

I'm two sessions into my "Bookhounds of London" campaign using the "Trail of Cthulhu" system. Prior to that I'd been running games for almost two years using "Call of Cthulhu",so I've been reflecting on the differences between the two games and ideas for the future.

First of all, I never stayed close to the actual game system when I ran "Call of Cthulhu" or "Delta Green". There were very few rolls of the dice, typically only for combat moves or sanity checks. If the college professor in the group had a solid background in history (40% or more) I wouldn't ask for a roll. "Trail of Cthulhu",as a system, is a perfect fit in that regard. No skill rolls are required if you have a particular knowledge, the rolls are for general abilities like fleeing or scuffling.

Secondly,I am more forgiving than most Cthulhu GMs in terms of survival rates. You don't see "Total Party Kills" in my games, and while a good portion of the group won't survive the whole campaign, they will typically make it to the last session. "Trail of Cthulhu" again is a better fit, the group don't feel the burn of injuries and sanity loss until much deeper into the game.

Speaking of sanity, the slow burn rate also means that I've yet to see the in-game effects of mental instability in "Trail" unlike "Call", so I can't really compare the two at this stage. I do think that this makes "Trail" a good choice for an epic campaign like "Masks of Nyarlathotep", where party casualties are commonplace and can make it harder to keep ongoing threads.

"Masks" is on my list of things to run next year, adapted to "Trail of Cthulhu". I'm also thinking of running adaptations of some of the "Call of Cthulhu" scenarios that I've ran over the years. Some have already been done and can be found on the Pelgrane Press website. I haven't seen one for "The Condemned" or "The Sanatorium", both strong contenders for reruns, but I do have adaptations of "Tell Me,Have You Seen The Yellow Sign?", "The Cracked and Crooked Manse","Malice Everlasting" and "Edge of Darkness". All of those games have stayed in my mind and in different ways influenced the games I ran afterwards. I may weave them into "Masks" or have them stitched together as their own mini-campaign. It very much depends on who plays..I don't want the same players to have played these before, so "Malice" and "Yellow Sign" would be the best ones to do.

Has anyone else tried both systems or conversions from one to the other? Let me know!
