HP 100's are nice but you should be using DIN with them, NOT saying that you have to, but I know a few people that the o-ring for the yolk plug slid out. Only one person using it, but quite a few when getting them filled on a yolk fill whip. The LP 95 is pretty much the same height but just fatter, also with a boat fill of around 3k it's WAY over a 100.
