i did a search for line counters and im going to get my dad a couple for trolling. i guess the majority of guys here think the shakespeare line counters work well....i think the way you can put them on any rod would be a plus. just one question, will they work ok with stuff like spiderwire or is that stuff too slick? is there just one kind of shakespeare line counter? if anyone wants to make any other comments at all, feel free.
