I've messed around with most brands in the store. Hummingbird definitely isn't as user-friendly as the other brands, but I think once you turn off some of the screen options you don't want and configure your presets, it wouldn't be too bad. I haven't checked out the connections in the back though.

I was thinking of the helix 9. Want something with a good size screen. The mega imaging looks amazing and I like the maps and different features that hummingbird has. I do look at Garmin a lot though, but most likely will end up going with hummingbird. Both look amazing though.

I'm in the same boat as you. Looking for a nice unit for my PA12. Really want to take advantage of the guardian system. Was most interested in a Hummingbird Helix or Garmin. As far as mounting the transducer to the guardian system, Hobie has a page with some templates you can print out and trace/cut/drill. From their website: Support > Product Support > Choose your kayak > under manuals/parts guide choose transducer mounting templates for Hobie guardian. They only have a couple lowrance, ray marine, and one for hummingbird.
