Sporran Straps: Leather vs Chain?

[Nathan]

Here's what I prefer: A plain leather strap (usually in a shade of brown, tan, or conker from McRostie) with my Highland day attire and a plain (smooth black) leather, sterling silver chain-link strap (Ian Grant) with my Highland evening attire. Though I have always adored this sporran and chain strap ensemble for Highland day attire:

I wear beveled leather strap with day wear and a smooth, high quality chain with evening wear.
