Stonfo Elite 528 Disc-Drag Bobbin Holder
The weighted Elite model with a hardened-steel outlet bushing and a disc to tune thread payout.

Description
The 528 is worth comparing if you want to set the drag at the spool and keep a regular-sized holder in hand. When you change to finer thread, use the drag to dial back the resistance before tying the first fly. When the thread path is the problem, inspect the outlet separately from the adjustment at the spool.

Fit and buying advice
Stonfo uses a hardened-steel bushing at the tube outlet on this model. If your work calls for more room around the jaws, compare the Compact. If material diameter is the limiting factor, compare the Elite 2's larger tube.
Questions about this tool
Does turning the disc change spool size?
It changes resistance to payout. The physical space for a spool is a separate fit question.
Which part guides the thread?
The tube directs it toward the fly. The hardened bushing is at the outlet, where the thread leaves the tool.
Which Elite model should I order for thick floss?
Compare the 578 Elite 2 first. Stonfo lists its larger tube for materials such as floss and microchenille.
