I agree the RT effect of the ULT + 1000+ psi is very fast. However I found it was also a nightmare to set up reliably. It would shoot great for a few games, then go full auto or stop shooting until the shims were adjusted. Getting it to fire long strings using RT's bounce effect was a difficult trick to master, not helped by increased pressures making return more snappy. I even tried a RPG Viper (roller trigger) in the Intelliframe, but still wasn't 100% happy with it.
The Egomag conversion isn't as fast as the maxed R/T effect, but it's far more reliable at realistic ROF. I've got a chop free 15bps out of it so far, with more to come with fine tuning. It also cycles ok at around 850psi which let's me shoot further into the tank. I'm really chuffed how my DIY Emag turned out
It'll be out for re-annodising in a few months, so I'll post some photo's of the rebuild.
