I have been using the 2in1 spinjag for awhile now and this year bought the loader only spinjag just to try. Both are good products and an excellent company to boot. If suggesting just one the 2in1 based on the ability to load and swab with just one jag for in the field use. I honestly don't see a noticable difference between the 2in1 and loader "only" in terms of groups.
