I think I have the Cubitron... Yes, it seems I have a box full of different grits,

Boxes were sealed, 'cept for one, so I'm guessing they were never really put through their paces, yet.

Sometime in the past I got sucked into getting the Mirka Galaxy,
 
I have the PITA in aligning the holes which I have been using on my Fe$tool upside down ROS.

The Abranet does rip easy, if you are heavy handed.  Since I realised how easily they rip, I changed my approach and they are now outlasting all expectations to the point that I haven't had the need to swing over to the Cubitron. I might just have to make the swing, even though I have a bucketload or the others, otherwise I may never use them.

I appreciate the "argument" of you have the sucker hose attached, so why the BS about the cord... well I have found that less the cord is one extra level of convenience... and at my age convenience is a close second to vino and ducking SWMBO's swipes. 

If your first cut is too short... Take the second cut from the longer end... LBD
