I use the Primos bowsling, which is simular for protection and carry...IMHO the best invention since the bow and arrow...
They really do protect cams/Idler wheels, strings and other major bow componants...worth their weight in gold right there...
Biggest asset is the carry...so nice..I chase a lot of elk...with elk you have to take them for a 7 mile walk in the morning just to let them stretch ....lol
So the sling carry is so comfortable and fast...another bonus is hands free ..to call, have a snack what ever...
That particular pack you bought [great deal] is more design for heavy duty full day adventures, would be great on horseback or climbing mountains...and overall bow and arrow protection...
I have my sling on even in the case in fact more so in the case because thats where many get damage with other things in a bowcase such as arrows...Yikes seen broadheads on those arrows in case...releases..etc things that can bounce around ...that case will provide full protection...
If you the type that heads out in the morning on foot and are out all day...thats a perfect pack/sling also...
Cant go wrong...as long as its quick release from bow...
