Using inline regulation and deactivating the internal reg, I've not had any problems with the 70 durometer orings I replace the stock ones with (10k+ shots). I am almost certain that new orings, whether 70 or 90 durometer, is a necessary first upgrade for any Gen 1 or Gen 2 (if not Gen 3) Thumper owner.

I'm just curious. Thank you for your input Flint!
Straight to 90. Went to a local supplier, and he had only 90ies.
Keep in mind that until today, my Thumper was on a shimmed inline reg, and co2 only (hopefully with the external reg, ill be able to switch to HPA)
