Stomatador, what kind of velocity were you able to get with H4831? I have a decent supply of that, and while I hear great things about RL-26, it also seems to have a reputation for pressure spikes at high ambient temperatures, which I would like to avoid. H4831 on the other hand, at least according to Hodgon, is temperature stable.
