I'm still waiting on those pics that Aaron took while doing the mod, otherwise I would have posted them. As soon as he gets them to me, I'll get them posted.
Upon posing further tests, the brick walls on our practice space seem to be the limit on where I get signal with the newly modded XDS95. That said, the mod can be chalked up to an improvement to an extent, because the building is 1600 square-feet, and I was getting signal from the furthest distance from corner to corner. There's some pathagrium theorum stuff that gets involved here, but you get the idea. Definitely more than the 10-20' I was getting in the same building.
The real test will be my next show. This will be a 4-day festival in June, with possibility of playing 2 or more different locations. I also have a pair of 7dBi antennas that I can try out. If it weren't for the fact that these are way too big for my board, they'd probably be in there already.
