Have you tried using 200 lb. mono "straights" instead of the mono loops? This was reccomended to me over the winter and I'm going to try it this year. If you can't get the straights I beleive you can cut spooled mono into 6-8" strips and then immerse in very hot water and then cold to get the memory out. Then drill small holes in the bottom of the pan, thread the straights through and melt the mono and squash flat on the bottom.
I like the idea of the slight flexibility of the straights when the line comes ripping out of the basket. I will let you know how it works out as soon as I get a chance for some "field research"
