has anyone ordered a DOUBLE sided monogram cake topper?

i am looking on the site weddingcuts..... they describe that their mirror acrylic toppers have the back of the initial a gray color..and advise that if the back of the initial may be seen ( depending on how the set up of the cake is) that you should order a double sided monogram...so the silver or gold will be on both sides.

iam considering this..its only about 10 dollars more....buti am wondering if that will make the topper too heavy??? any thoughts? ty!
