This is my first Pan Sling but I do have slings from other manufacturers. I love the way this sling feels vs the others and my directional control seems much better with the SR3. I've also bought one for my 8 year old and he's picked it up quite quickly and loves his Deep SR3.
As a side note, my sling was initially lost in transit. Pan Slings kept in contact with me and the courier company, regularly tracking the item and asking the courier for updates and sharing any new information with me until it arrived. Absolutely brilliant customer service! Fantastic experience with the product and the company; I'll be a returning customer for life!
