I don't do enough drywall to justify a planex, but was looking for a quicker sand for a bigger job. Usually I use 220 Brilliant with my rts400 on smaller jobs like patches or bathrooms, but was wondering if anyone had used an ro150 for drywall. It appears to have the same stroke as the ETS 5mm that Festool recommends. Is tool weight the only issue here? I'm sold on Festool's dust collection, and don't really want to go back to a pole sander, but I don't want to stock another line of abrasives for a different size sander as well. Is this a good place for an interface or soft pad? I hook up to a powerful Nikro vacuum, but could pull a weaker Shop-vac out of the shop. I do drywall enough that I'm planning on keeping it in orbital mode! Thanks!
