I've always snelled my circles as well but could see where a loop would help the circle move into the right angle.

And for all the guys questioning the effectiveness of circles on tip ups. They work either apply steady pressure while the fish is taking line to let the hook do its job, or loop a ruber band on tip up line about 10ft up from the depth you wanna fish, then loop the rubber band around the tip up spool. Wind up the tip up to your depth and set the tip up. That way the fish sets off the flag runs about 10ft and the catches the rubber band which adds pressure hooking the fish, if it's a better fish they will break the rubber band leaving it free to take more line with breaking the line. Also a good way for finicky trout and other species that tends to spit the bait. If you don't get to your tip up fast enough
