Musashi, a premium 7068 bimetal that according to most, is the best all rounded for competition from all Sengoku models.
And the best news is that most b grades are smooth! so performance wise there is no difference with an A grade besides a small cosmetic ano flaw in the centre area! for half the price! And supper matte Blue is the best looking color for that throw.
