BLNR or SD43?

[Dibbledabble]

Hi, looking for some advice but appreciate it's down to personal opinions only.
I am next on the list (hopefully this month) for a BLNR at my local AD but the new SD43 has got me doubting if I am making the right choice. It's for a daily watch for all times (work in a suit). I used to have a LN GMT which I liked but sold it a few months ago to try and justify the BLNR given how close the watches are. I bought the LN about 6 months before the BLNR was released in 2012 and always wished I had waited with hindsight.
The appeal of the SD43 is that it is a little bit bigger as I'm quite a big chap and I always think 40mm is quite small. The option to try them both on together doesn't exist unfortunately nor does buy them both! I've got a good relationship with my AD so whilst the SD43 might be a longer wait I don't think it would be too long.
Thoughts from forum appreciated.
Cheers
