Jude 12 Variants [Updated]

I was translating today for my Monday night Bible Study and came across something interesting. To refresh your memory - The Book of Jude concerns ungodly men who have infiltrated the local assembly. These men are described in Jude 12 by the following BMTT [Beth'sMomToo Translation]. I'd like to show you how it all indents and lines up, but this format won't allow it - So imagine each comparison indented & lined up to together under "These are..." and the "who/which are" indented again and lined up under each other:

"These are
the (morally) damaging reefs/sunken rocks within your love-feasts,
who are boldly/fearlessly feasting themselves together (with you), [continuously]
who are feeding/sheperding themselves [continuously]

clouds without water
which are being driven about by the agency of a strong/tempestuous wind [continuously]

fruitless autumn trees
which have died twice,
which have been rooted out/plucked up by the roots."

The word for "feeding" also refers to shepherding. There is an VARIANT Greek text instead of "who are feeding/shepherding themselves" that offers the following translation:

"to whom you are feeding/shepherding" [continuously]

Both of those variants are interesting. The first one gives me the idea of the member of a local assembly who does not submit to the leadership and insists on shepherding/feeding himself. (We've all seen that occur).

The second gives me the idea of the member of a local assembly who constantly demands/requires feeding/shepherding - the person surrounded by turmoil who never learns or applies the knowledge he is given. THAT kind of church member is equally familiar. Either would be a danger to the rest of the assembly.

A simpler [K.I.S.S. method of interpretation... which is probably better than my vain imaginations] interpretation of this metaphor, into which either variant fits nicely - the idea that these people are right among you in the assembly... participating in worship alongside the believers... looking just like a believer on the outside, but being "ungodly men" in their hearts, i.e. unregenerate.

So...I like either variant and it seems to me either would fit into the context. What do you think? Is one a better fit than the other? How do you think the metaphor best applies to the subject/context?
