Nope, thats the only way. Remember you can also lengthen a rig again with some line. I wouldn’t with carp or big fish rigs, but have been known to put extra line on river rigs. Say if my mainline is .10mm I’ll add the required length of .12 or .14mm.
I never store rigs with hooklengths on, as I never know what I will require in any given situation. After a session I stick the whole lot on the winder and put it back in the tray the wrong way round to show it’s been used, and invariably I’ll remake rigs after two uses at most. Only tend to use them twice if I am visiting the same venue.
