they are all very nice markers and have owned and shot all of the sl markers personally i think the sl66. On the other hand they are all pro level markers that have crucial changes added to them compared to the standard of that gun years marker.
ive heard lots of talk
what is the best sl marker
I think you left out the best and most rare sl model.....the SL91.
I collect markers, some of the collection
