You might find this interesting. I followed this approach instead of preboiling on my last batch.
Full disclosure, my newest fest bier I did preboil, no sparge, and use both smb in the strike water and polyclar in the whirlpool. I'm open to anything, but I'm coming at it from a slightly different angle. I love my beers, but would like to reduce lagering time. I find that gelatin is not the same as aging. I blame the polyphenol Boogeyman.
I still have a copper pick up tube. I'm convinced that it's essential for classic Belgian styles. But I have seen improvements in conditioning time for this beer.
