I uses the Vise finger tape, tan in color. Wrap a layer around the base of my thumb at the web, and then a second layer overlapping to about half way up my thumbnail. You do have to wrap the tape firmly, but I have had no problems with circulation.
The tape is not thick at all and for me is no different than puting a piece of tape in my thumbhole. I do recommend cleaning your thumb with alcohol or baall cleaner, whatever is handy, as it will help the tape to stick to your thumb.
The tape will save your thumb. Experiment with it and give it a chance. Once you get use to it, you will get a more consistent feel than without it. It is much better then the skin patches.
