I actutally own both bows Seem to aslways have two Mathews. THe biggest difference that I seeare as follows;

1. The Switchback draw is smoother.

2. THe draw lenght in the Outback needs to be 1/2 longer in order to compare. For me a a 28.5 in SB and a 29 in OB to shoot similar.

3. SB is faster will exact same arrow

4. OB is much easier to tune than the SB. The SB was the most difficlty bow I have ever had to tune.

All said I would get the Switchback Simply because wone it is tuned there is no better shooting bow on the market . I have never been able to shoot as well as i have right now. I am consonstently getting 4" gorups at 40 yds and that pretty good for me.

Hope it helps!
