Personally, I don't see the point of sending a duplicate bass signal to the mains and the sub, in fact I just wouldn't ever do it. LFE is tricky and you are more likely to muddy your bass and affect room modes and create nulls than you are to help it in any way. JMHO.
Actually, based on many personal room measurements, your above is fact, not opinion.

Depending on your speakers, your mains may play a cleaner 60hz than your sub, in that case, if it sounds better for you having your mains play it, adjust the crossover to 60hz, (or wherever the sub starts playing cleaner bass to your ears). This is usually 60-120 hz, YMMV.
Currently, our mains and center channel are crossed over at 40Hz and the surrounds are crossed over at 60Hz (mains large, center channel and surrounds, small, LFE+Mains @ 120Hz) all settings have been verified by countless room readings to provide the strongest/tightest measurement. No room treatments allowed.
If a few days, a third sub will arrive and I'll play with this third sub to see how a third sub impacts a particular life sucking, 80Hz null I can't get rid of.
So far, where the rubber meets the road, the only things I've found that aren't out to lunch are, Audyssey, DSPeaker, (Anti-Mode), REW and a way cool sound level meter I found that didn't come from Radio Shack. Everything else is subjective personal opinion or blarney and if one likes going crazy, needs to be taken with a grain of salt.
I've found, part of the bass management problem lies in the fact that most don't understand the purpose of LFE and that it's an "effect" not a constant source sound. If one approaches the LFE channel from the view that it's suppose to be heard 24/7, then the LFE channel is not being set up properly. Then there's this whole "reference" thingy that's not being held to real world standards and I find the use of which is being abused as opposed to being respected and not used for it's intent, headroom for momentary "effect."
The point of the above babbling, it was very gratifying to read what you posted in your above, or if you will, your words were the proverbial breath of fresh air.
