Dan, I've managed to cram in a useful PF setup in my LS6 (small panel), if that helps. I use the brick as my primary GPS and igc logger, driving my SN10 and Oudie2 - which both by the way have their own Flarm displays and warnings, so you could get away with the little LED flarm display. I also have a Zaon MRX and use it in our towplanes and club gliders, but the PF has the huge advantage of also showing ADS-B equipped aircraft, and they show up really well on the Oudie map (you get what you pay for ;^).

I think LK8000 shows flarm traffic? What about TopHat?

Anyway - I feel blind nowadays when I'm flying without good traffic detection - and nowadays there is really no good reason not to have it - and the combination of a Mode S xponder and a PF is about the best setup you can have (unless you can fit an APG-82 AESA radar in your glider...)
