When your programs and registers will fit in a smaller space and you want to be able to reasonably use WALL.

Just on principal, conversions to a CL by using a C seems less 'wasteful'.

Also, using a TK HP41C 'restores' and upgrades a rare and fun variation of the 41 series.

I wasn't able to use my TK since it had the wonky internal connector, and, LOL, I wound up converting a 41CV anyhow.
