Well, the basic CRLs reflect the image of the typical Sandtrooper. This can be recognized by the shoulder pauldron. I do not understand the problem. If you value having a TD without a pauldron, try to reach level 3. The TD without pauldron would be a step up to level 3. At level 3 the CRLs dictate that you emulate a specific TD. Means identical in armor (special features, damage, match) and weathering. A 1:1 match to the film model that is as accurate as possible. For me, simply leaving out the pauldron isn't an improvement if the rest doesn't fit. Sorry.
If it's so important to you not to have one, then rent a pauldron, add the basic and leave it out later.
Thanks, Thomas
