Congrats on your new climber. Yep, most of the newer ones have done away with those wingnuts and v-bars. Climbing is much easier with most modern stands, especially those that have a bar to sit on. Just make sure to follow the instructions/video and practice a few times so your stand becomes your friend.
To make any stand even quieter, first check all(if any)moving parts. Adding a nylon or plasticwasher where bolts/nuts pivot on some stands can work wonders. Alsoadding foam pipe insulation to the arms and either tape or using tie-wraps to secure itis good if you rest your bow across your lap. Anotheris to add adhesive felt where the top and bottom nests together while packing your stand. Its thin so your stand will still fit together well and will stop clanking while walking. Also, if necessary buy a bungi cord to strap across the top and bottom, it will even fit them together tighter, allowing no noise at all while packing in and out.
