Sorry to hear about your wrist. Hopefully with the surgery and the plate it will heal well and give you good functionality back.
Here is a short thread on the subject which would tend to indicate no obvious issues. However bear in mind that you are not going to be able to get 300 “usable” units from the tslim after you get priming into account. So if you are really at 150 ~ 155 units every three days, you are likely to run a little short on day #6.
