Ritual Path Magic - Basic vs Effect-Shaping

[Moneval]

Hi all.

I'm working on a campaign where I'm planning to use RPM as my main magic system, but am having trouble deciding whether to use the default system, or the Effect-Shaping variant out of pyramid 3/66.

As far as I can see, the basic system seems to fit better with a lot of the expanded stuff for RPM, but I feel like Effect-Shaping more closely matches how I want magic to work, while also removing the burden of tracking energy accumulation. But I haven't really run either variant before, so I'm hoping to hear people's experiences with either/both versions.

If it helps, the campaign is science-fantasy with magic that should ideally have a ritual, occult feel to it, closer to an urban fantasy or pulp magic system than a traditional dungeon fantasy system.

Thanks in advance!
