NJ Devils fan - well I am a big fan of Clown Loaches - and IMO if you get the ones that are 1" to 2 1/2" now - you won't have any problem for 4 or 5 years. they do get big but they do grow slowly. I have had 3 in a 29 gallon that started around 1" and in 2+ years grew to the 2" to 2 1/2" range.
So, I say get the clowns - and if in 4 or 5 years they get too big, then trade them in at your LFS. A lot can happen in 4 or 5 years.
BTW - In my new tank (the same 72 gallon bowfront) I have decided on 2 bristlenose and 5 or 6 clowns (plus one existing yo-yo loach) as my cleanup crew. the bristlenose because the clowns I have had don't really touch the algae - and the clowns (who by the way love bloodworms) because I enjoy them a lot and they do scour the bottom picking up food that has fallen there.
good luck
