I have not used the trantula spring but I can say the e3650 is more or less streight drop in... JM has a good reputation for his springs and if you look at the Jay Morgans Whisper tune thread you can see the results we had with an apex small seal and the e3650 spring....

In other words I personaly would reccomend the e3650 right now but I have no experiance with anything else so I am kinda biased :)
