I run both, but for browns I like the big boards... When I fish walleyes on LO I run the offshore inlines with the upgraded or-18 snapper clip (keep the board locked on the line so you can take it off)..... some things to consider: big boards allow you to run more lines, big boards are more user friendly for multiple hook ups, big boards dont pass directly over the fish, big boards DO have lag time and inlines if you lock them on the line dont (thats why I use the inlines for LO eyes, BETTER hook-ups), inlines dont run as smoothly if you have drematiclly different pulling baits (they dont run in formation well with a big deep RR and a shallow small stick at the same time), inlines are easier to put out for just a couple lines, inlines are cheaper if you run just a few lines, inlines can be harder to read with a small fish
But theres a tool for every job and to each their own..
good luck!
