the difference between sherrils 12mm and wesspurs 12mm dynema loop runners is life & death. the color pattern is the same and sherrill will match the price and give u 10% off of the difference. sherrills runner are much stronger at a 27kn abs and wesspurs cheap knockoffs are rated at 22kn abs. sherrill also sells u what is pictured in the catalog and wesspur is misguiding u and showing a pic of a 5/8 spectra runner and giving u a cheep 12mm dynema runner. wesspur does not even picture a 12mm dynema runner anywhere in there catalog. i think wesspur is very unprofessional and will go 4 cheaper products over quality any day of the week. they also will give u a pi$$ poor attitude when u have any problems with your order. most of the time they are willing to refund your money but will short change u on the shipping. i think wesspur stinks and will absolutely never spend another penny with that lousy unprofessional company ever again!!!!!!!!!!!!!!
