Glad you found something you like. I hear you on that annoying float on speedplays when you are not used to it. It took a while but now I prefer them to other pedals. I guess I like the fact that there is barely any pedal there. As far as dropping watts on them, go as hard as you want and they'll do the job. I'm still a big woman and have had dumb momments and climbed hard hills on my 52 thinking the pedals would come off or I would unclip, hasn't happened yet. In fact all the guys on our mens team use them without problems, and you can be sure they produce more then 1000 on climbs and sprints.
