Thanks for the feedback. Ultimately I ended up getting the wired Strada with cadence. I spoke with LongBikes, the maker of my Slipstream and they provide a custom mount for the cadence sensor. Due to the configuration of the bike and the location of where the computer head unit is mounted, the speed sensor must go on the front fork and the cadence sensor goes on the lower frame tube just behind the crank bearing.

I thought about going wireless but there are just too many reports of flakey behavior from electrical interference and/or weather to my liking.
