Sporran cantle options

[Manu]

Greetings rabble,

I'm in the early stages of commissioning my next sporran. I plan to acquire a nice high quality piece that will cover me from casual/relaxed traditional to black tie. I am following wise advise to buy once and buy well. Anyway, so given all these MoD restorations I have seen popping up, gave me sporran envy, and after a long tedious search I found a source that'll make it and has a brass MoD cantle available.

I'd like to get input on the appropriateness of a brass cantle in black tie. While those will be very far and few in between, given the cost of the sporran I'd like it to be the one that serves all purpose. The other options are the more commercially available polished pewter cantles, which I like a lot too, and also drop the price of the sporran by 60 pounds. Thanks in advance for your input.
