I hope this helps illuminate one person's views of the D10:
Approximately 100+ dives over 8 months and it is still going strong. Water temps vary between 41 and 58 with smart wool base layer and a 100 gram MK1 from whites during the coldest dives. Above 50 degrees and I am wearing only the MK1 coverall. Minimal buoyancy effects from 30-100+ foot depths. No noticeable squeeze till about 50-60 before I inflate for one or two short burps. This is a personal preference! Good cushioning from bottom obstacles. I use wet and dry gloves. The neoprene wrist or cuff protectors had to go when I installed Kubi rings. Bummer. I since lost the cuffs and cannot find replacements. It's a double bummer.
A little less dexterity on reaching double valves. I dive mostly side-mount now so this is no longer a concern. I repositioned tanks and and wing to overcome this challenge. I also stretch my arms prior to valve operation to gain a little more reach. This is a slight tweak an ol' timer taught me years ago. A little excess material along the forearms areas. I had to rethink my BP/plate donning and removal sequence during the first months. One concern as with any neoprene drysuit: over heating at air temps above 80. Eh, I just enter the water sooner than my fellow divers by a few minutes.
I carry 24-26 lbs., total to include BP; empty tank/vale combo and regulator setup for single HP100s. I try to distribute the weight so my belt lead is for the max gas consumption. I usually end a dive with 600-800 lbs at the surface. I occasionally carry 2-3 extra pounds to offset a few more bumps of air at depth. I carry less with double back and side mount configuation where a deco or BO is attached.
The boots are a little too flexible for me. I installed really solid ortho-insoles to overcome walking on rocky shores and give me better balance. I used wool or fourth element socks to keep warm and allow circulation. I may install new boots this year. The suit has saved when on the occasion a wave crushes me during exits and I take a fun tumble. Knee pads are long, thick and durable! If I am diving in rough, cold waters or extended deco dives this is my go to drysuit. I have a trilaminate for those fun dives on near perfect conditions or for 30 minute shallow depth, archaeology surveys. I got my large for 1/4 the retail price during a special event. Hands down the best $450 I have ever spent (period).
