The Assaults and the Williams 38c's are quite similar, carbon clinchers, the Assaults are 46 mm, 1525 grams, the Williams are 38 mm, 1462 grams, so pick your weapons. Six of one half a dozen of the other (I think they're both about a grand). I can speak from personal experience that Williams has better support than any large company, you call or email and Keith Williams responds personally. His product is very high quality and his service is the best.
