Terry,
the Safari and "SL" versions operate exactly the same........the Safari just has slick tubes and the SL doesn't. I got so used to loading the original one I had from the backside that it's second nature to me now so I dont think about it.

In actuallity the "SL" will be a touch QUIETER because you will use the supplied felt on the launcher which is WHISPER quiet on the draw and shot. The Safari has just a slight hiss to it for the short time that it is in contact with the shaft on the draw.
Nothing to worry about but the SL is a bit quieter.

I'd feel just fine hunting with either.

The rest tuning and set-up is a breeze.

I can tell you right now, just air it out to the left for the Allegiance and start there for paper tuning. Mine was perfect right there.
The timing adjustment is simple......there is a set screw in the launcher arm to set cord length.
All you need to do is run the cord through the hole in your cable slide,(Hopefully your slide has a point of attachment?) knot it off, clip and melt.........then run the other end to the length you need with the set screw......when you have the timing you want, lock down the screw and clip, and melt that end. DONE.
Start on the long side, and work your way to the desired length........start too short and draw and you could snap off the slide peg.[:-]

I have mine coming up to full height right about the front of the valley. It supports the arrow for about 3" +/- of travel when fired.
Nock height is level, and arrow is even with the center of the berger holes.(That is the set up and tune with my "E" cam Bowtech, yours may vary on your Reflex)
