I hunt sw coast range late archery just about every year in a 3pt or antlerless unit. The bulls are solo unless they are spikes or little rags with a herd and tend to tuck away and hide. Focus on finding small groups in all sorts of spots. Little pockets or blind spots in reprod that are not visible from the driven road. I'm not saying away from the road, just where you can't see them. A lot of times the 2 or 3 will tuck in these little patches to feed or bed and aren't noticed till you go over to look off a ledge or around a bend or ridge in a hill. The elk are skittish already and if you try and target larger groups it gets significantly harder to stalk with that many more eyeballs.
As for gear, solid rain gear is a must. Use weather to your advantage. Pray you don't get freezing dry temps since it makes the woods pretty noisy. Bike behind gates if you can. keep your binos dry. Cow call only for stopping or trying to redirect a spooked herd/slow it down. If you by chance split a calf and cow, and she becomes out of of sight from the calf you can sometimes coax the calf into your calling. I like to hold my bow by the riser with a hand warmer between my hand hand grip to keep some dexterity or a water proof glove if you can shoot with gloves on. Also the days are short so pack a headlamp and flash light incase you do shoot one in the evening. Spare set of dry cloths if you plan to hunt all day and it's a soaker out. Staying dry and warm keeps morale in place, and leads to you spending more time and effort chasing animals and thus more chance for opportunity. Hope this helps a little!
