TeamCasa,
A couple of tips.
1) Get some KY Jelly if you have Latex seals - makes getting in the suit easier and is not as messy on the seals. Use unscented talc for storing the suit.
2) Practice shallow for a few dives - the shallow practice is what you need for comfort and getting your bouyancy right for stops - for example OOA and attaching/detaching the drysuit inflator hose - do it with your buddy -you'll get some good buoyancy practice.
3) Do a weight check as soon as possible
4) Inspect the zip before and after each dive - ie don't stress the zip and make sure it's lubed a lot.
5) If you have any aspirations to use doubles don't use the suit for buoyancy - use the BC and remove squeeze - this might be debatable for some people but try point 2 with air in the suit and then without and see which feels more comfortable in terms of buoyancy control.
6) Try reaching back for your tank valve in the water - this can reveal how good a fit the drysuit/undersuit is or highlight a potential trim issue.
7) When you put your drysuit on, pull the undersuit upwards towards the sky - this might give you a little more flexibility.
8) Have fun
