After years of struggling with inadequate/non-existent DC, specifically TS overhead, I've finally made the decision to upgrade (hopefully) from a Delta 760 DC and 4" flexible hoses for my 1-bay garage setup.
A major goal is TS overhead dust collection for my lungs. I'm uncertain as to what size piping I should be considering, and therefore cannot filter through all the options available for retail purchase:
1. 4" reduced down from the (planned) 6'' main
2. 2.5" reduced down from the (planned) 6" main
3. 2.5" from a dedicated shop vac (least preferred due to needing to turn on two sources)
Given the three possible scenarios, which would likely provide the best overhead DC for the TS?
For the curious - I just purchased the Harvey G700 during their BF sale. This unit checks a lot of boxes for me: small form factor, duct location (not wanting overhead), and ease of waste bag cleaning.
TIA
