Trisuit for 1/2 or switch up

Here is my delima.  I have raced sprints and olympics in a zoot ultra trisuit all year for and really like it thus far.  I have my first half coming up (Longhorn 70.3).  I do my training rides with trishorts I have one pair of aevero and one pair of zoots and a couple old tritops.  The shorts and tops are all to large for me, they are size large and I know can wear size small.  Yes I  have dropped close to 40 pounds since I started last summer. 

I am concerned about about bathroom breaks for the 1/2 and how much time it would cost me and also with just using the side pockets for my shotblocks on my trisuit.  I may practice with the suit this weekend on my long ride with the blocks and see how that feels.

Does anyone else use a suit for long distance or do yall advise getting shorts and a new top.

Also has anyone used Aevero shorts for long distance.  It may seem like I am trying to skimp but just signed up for IMKY and mamma if starting to frown on the price of triathlon right now.hehe
