I use 5 and 5.6 my favorite is a 5.6 b&m sharpshooter...the longer rods seem alot more accurate to me I have a 4.6 sharpshooter that always seems to hit high to me so I leave it at the house (going to sell it). The easiest rod to learn to shoot with is a 5ft ugly stick because only the end portion of the rod bends, and u ain't gone break it!
