I always use pressure to me it's OG because it's not as distractive and having a view of the pressure while keeping everything simple and clean is a big deal to me, velocity might be a bit more advanced version but the colors I hate, and persistent is annoying, fire and blob look cool but aren't too useful.
Idk :P I also alternate between pressure and heat a lot to see how hot the entire thing is, it's really cool!
Lol yeah but pressure isn't bad...the glow is extremely helpful, about in most situations I would like to see how much pressure is at some place, and it's dead simple too (all it is is blue and red).
But lol, a plain view would be good too :P I'm surprised no one ever suggested that xD
