I have and use both types. Either can fizzle in damp weather, or work just fine. First thing our OP need to do, IMO, is learn the rules in WA. If he goes traditional, no problem. If he wants an inline, Knight makes models that meet the Western regs, as may other makers.
When I ordered my new Ultra Lite, I specified Colorado Legal, which has sights and legal breeching for that state, and is also D&T'd for optics. A percussion bolt and plug would, I think, make it WA and OR legal, not that that's ever gonna happen. I just wanted every option on the table. i also got the nitride over SS finish. Replaced the rear leaf with an aperture, which may not be legal on the coast. No question about Knight quality,if you're willing to spring. If one of the less pricey ones will meet the regs, go for it. Midway has, or had, good deals on Knights. You order through them, the rifle is built and drop-shipped by Knight. I saved maybe $200.
