Btw, these work really well with the Wulff Ambush lines. There lined perfectly 2 weights heavier.
For example. 5 weight switch would use a 7 weight Wulff Ambush.
Grain weight is 140-280 for the 5 weight: 7 weight Ambush is 265 grains.
Grain weight is 160-330 for the 6 weight: 8 weight Ambush is 290 grains.
