I have frontloaded EQ, and it seemed to work quite nicely for me with no sides or bloating, and started working more quickly. I don't, and wouldn't frontload test though. (Also wouldn't recommend frontloading EQ if you are the type to get anxiety from it)
To me the logic of it is to acheive peak levels more quickly, admittedly at the expense of unstable blood levels and increased chances of sides at the outset.
Ultimately you gotta do what works for you, and I do agree that a kickstart with an oral is generally preferable to a front load with a long ester.
