SWIM's had the fortune to try a few different strains of p.cubensis, and has noticed that each strain seems to have its own 'signature' trip. Even when SWIM tried some shrooms and didnt find out what strain they were until after the voyage, he was very interested when he found out that the trip he had the night before coincided with what he felt that particular strain should produce.
For instance:
Equadors - very 'clean' trip with minimal body load. Great visuals, more towards LSD-type patterns. Nice psychedelic 'sparkle'.
B+ - Intense euphoria eclipsing even an MDMA experience at some points. Visually intense, shapes morphing and flowing into eachother. Heavy bodyload, but in a good way...a bit of caffeine is almost always necessary in the latter part of the trip to keep from being glued to a comfy chair
Perhaps it is all in SWIM's head and he has the trip he is expecting. Or, perhaps there is a difference in dosage here providing the varying effects.
Either way, its interesting.
