Glass on fin and rovings

Agreed, except for more than a 1/4" change in placement. A whole lot easier to grind/break off a glass-on to move around than to move your fin boxes.

True for a Futures Box. But not a longboard 10 1/2" box. Not to mention that it is fun to change fins. Easily changing fins in even a Futures or Fusion box.

Well of course! However, figuring out placement on a longboard single fin is much less likely to be questionable as opposed to experimenting with a new shape twin, quad or thruster. Made a few fish shapes that I wasn’t sure where I wanted the fins. Once I knew the placement was okay, I installed boxes for aforementioned fin changes and/or travel.
