What else out there for experience? Blatz, did you use these yet?
yeah - we had a festival here 2 weeks ago and I served 20gal of my west coast IPA - 10gal with simcoe/amarillo dryhop and 10gal with mosaic/calypso dryhop. obviously, with all the hops in the kettle and then using 2 hops in the dryhop, I didn't get a pure mosaic impression, but I thought it was fantastic - next time I am doing all mosaic to see how it ends up. From what I got when I pulled the hop bag holding the mosaic: very tropical fruity and piney without the pungency of simcoe, but overall it thought it was very close to simcoe and I like it alot. I wouldn't say its much like Citra, but I need more experimentation.
all that said, people at the fest seemed to prefer the simcoe/amarillo, but I think that may have been the calypso's fault
