SOTO is selling some balls for TrackIR user on www.checksix-forums.com. AFAIK it works better that NP reflector tape.
As long as you don't mind wearing balls on your head.
The sphere should reflect better, but I found the reflective tape (which is designed for reflecting at acute angles) to work for 40 degrees left/right of boresight, which is all you need.
