IMO. I have fished a lot of both types. Spawn sacs are a East Coast / Great Lakes things and I used them exclusively when fishing for Lake Michigan Steelhead and Browns. They do work well for those fisheries, but they are a pain to tie up. I also think that once anything starts mouthing your eggs, you are going to get egg crush no matter what and spawn sac material does little to protect it. So why take the added time and expense to tie up spawn sacs? The ONLY reason is if you have individual eggs that you need to group together. IMO - the PNW way (clusters) is the way to go.

BTW - I have all the of ingredients to tie up 1000's of spawn sacs, brand new in the PKG that I'll sell if anyone wants the stuff. That should tell you everything!
