Yes, change the insert and it would look pretty good, I assume a standard sub insert would fit fine. And I must admit, I do like the red writing and also the markers on the 'ROLS170' model, makes for a distintive face. I guess if you didn't change the insert it would be even more distintive, but maybe a bit silly?! However, I'm not quite sure it's nice enough to make me buy this instead of the 5517 military sub on nato strap Silix has though! Wouldn't need to change the insert 'from the box' as it were on that too. Hmm...decisions!
Oh - something else popped into my mind - maybe from these we'll see a half decent rep of the Milgauss referred to above at some point too since they've got the basis?
