Yep, familiar with Dave Spounagle's build. I'd say that build is the hottest 6.9 I know of on here or FTE. I'd love to build a better IDI than that, but I'd settle for just that good! I have my ideas I've floated around here, no secret, just need about 3000 bucks and a good 6.9 core and a DB4 for a marinized GM 6.5 to rob for parts. At least I think that a custom build up like that could be potentially very cool....
