Central Texas. I assume the challenges you refer is getting wire down walls that were previously foamed? Not really too challenging at all. Nothing a glow rod wont fix. The bigger challenge is always damn fireblocks. But, we dont do too many retro's. SO nice to work in attics on a spray foam job. No looking for rafters to step on, MUCH cooler spaces and wide open work area.

However, I agree most WAP's are not attractive qand some are down right obtrusive. Ubiquiti has the best looking, IMO, and the "flattest" install. But we stopped using ALL Ubiquiti products months ago and rid ourselves of that silly control/AWS situation. Life is so much better now. :)
