Bill,
We are looking at having a bigger one made. I would like for it to be 8.5 - 9oz so it could easily take a full cup. We just need to figure out the diameter of the tube, thickness, etc (I don't want it to be real long or real fat - looking for that balance). Hopefully it won't be far out. Just need to nail down the specs. If anyone wants to chime in with their input I would be very interested in different perspectives.
Thanks,
Jason
