The 7000 last is indeed a very beautiful last however I find with that last (and other JL last) the heel cup seems to be relatively big. This is the problem I find with JL. Despite having quite a few JL in the past, I had to sadly find them a better fitted owner.
You are lucky if your feet fits like a glove on the 7000 last.
I am considering to sell some of my RLBL suit collection and just trying to gauge any interest. One is a Navy 36S suit (very rare to find size in this staple colour) and a couple of other 36R RLBL suits
I have yet to have the time to post pictures etc however if you are interested please don't hesitate to PM me. I will also offer a good deal for multiple purchases
