Very awkward spot to have pip too. The first time I pinned some kappa prop and that shit had me walking funny for a few days. Felt so weird to have pip in hip joint area.
water based is faster acting but far more painful... tne is the safer option as these guys said oil doesn't carry bacteria as easily as water but good suspension would be better because most guys pinning it want instant results and not sitting and waiting like 60-90 minutes for it to peak. you can get water based with less pain. you have to use micronized powder or it hurts like hell , made correctly you can shoot it thru a slin pin with no pip...
