I added a Raymarine ST60 wind instrument several years ago. I'm generally happy with it (and it matches my other ST60 heads), though have had to send the head back to Raymarine for repair. Don't know much about the wireless instruments from Tack Tick, though have read good things about them, plus no cable to run. Regardless of what you get, you'll need to fabricate (or buy from Selden) a mounting base for the masthead, as there's no room on the masthead to mount the unit. I actually have a picture Lew took of my masthead when he installed the bracket from a cherry picker - I'll see if I can find it.
Edit -- Pix attached. First one shows the Selden bracket attached, second is after moving the anchor light to it and mounting the wind instrument.
