Thanks for the info but I ended up buying it anyway and lucky me, it fit just like the original. So I can actually use it for a fast fly set up. Glad you responded because I forgot I even posted this. Now if anyone else has the same issue, problem solved. Only reason I or anyone else with the sl3 would purchase is because the sl3 equipment is all discontinued...
