I like collapsible sticks myself (in the form of a bipod). They can be pretty compact until needed. I've tried a tripod but it was a bit awkward getting set up on rough ground. Sitting with a hasty sling and sticks is almost like a bench for me and sitting just with sticks is pretty close.
Several years ago I had to shoot a bull at 250 yards from sitting with just a hasty sling because I was in knee to thigh high oakbrush that was too spindly for a rest. I wasn't carrying sticks which would have been better but two shots in about 2" caused him to stagger a bit, but he didn't move out of his tracks.
