Sub/Main speaker rolloff

I'm using a Velodyne sub and a pair of Polk bookshelves (with 5.25" woofers).
I have my sub's low-pass crossover set to 100Hz, and its high-pass crossover set to 80Hz.
My question is, is 20Hz of a "blend" adequate, or does it depend on personal taste?
My sub's low-pass crossover can go up to 200Hz, but I'm not sure whether that'd be really necessary.
What's your preferred amount of "blend", if you know what I mean by that word, between the sub and main speaker units?

I try to keep 20 Hz. No missing info, and I also go as high as possible to ease the load on the mids.
I do mine in the receiver for the HT. -
Gordon, one thing to keep in mind is that the numbers on the sub's crossover control(I assume that you don't have a receiver with bass management) frequently are fairly far off from the actual result; e.g. a 100Hz setting might actually take place at 80Hz or 120Hz. Checking with test tones to see the real effect can be done. Regardless of that matter however, no overlapping of the crossover points of the sort that you describe is necessary to get a good "blend". There's no sharp cutoff to the speakers below the crossover point or to the sub above the crossover point; it's just a rolloff. So, if you can accurately set both of the crossovers to 80Hz, there'll be all the "blend" that's advisable.
