What's wrong with EasyGPS? I've always used it and I've never had a problem. I'm using an eTrex LegendC, an eTrex Legend, and an Oregon 450t. I've never noticed any less info on the 450t than on my Geosphere App (ok, well, maybe a couple less logs..5 instead of 10 but not enough to not use it). I have trouble using GSAK. Or is it a "what you like to use" thing?
