I have the 28.
Kind of a funny story. Due to me being brand new to this, once I got the correct blade holder for the SC, I must have gotten really lucky, because it did a great job with very little tinkering on blade depth and pressure and such. The titan2 came in, and at first I thought it didn't cut nearly as well...but after quite a bit of fiddling it does a great job. Either the Titan2 is more finicky than the SC or like I said I got really lucky with the SC. I found on the titan, the tiniest adjustment on blade depth, (I mean barely moving it) made quite a bit of difference, and a little adjustment on pressure (the SC didn't seem to make much difference) I got it dialed in. Sometimes the adjustments seem counter intuitive, some a's and s's (with this particular font) were pulling off, so I thought it wasn't cutting, and applied more pressure, and it didn't help. Dialed the pressure back and it got better...so I kept lowering it until it seems about perfect now.
