Holdfast Money Maker | Initial Thoughts
So, I've used the Holdfast Money Maker for about three weddings now, so now I have more experience with it and can share some more of my thoughts.
Seriously, this thing looks really, really awesome. It actually looks more awesome on guys, in my opinion. Tyler looks great with it on when he's wearing a dress shirt (Photos later, when I get around to getting my film developed.) The straps got uncomfortable after the first few hours of the day. It's stiff leather, so it does get more uncomfortable than something like the Black Rapid's dual strap system, which I assume is soft and cushiony. I found myself adjusting and moving the straps around like a backpack, but only recently I tightened the strap up about three notches. I think that because the Holdfast is so straight and stiff, it might be better suited for a male body, which usually has a straighter torso.
Another thing I noticed is that even if I'm wearing a long sleeved dress shirt, I still feel the straps chafing my skin. I'm not sure if it's because the straightness of the Holdfast is competing with the curves of my body or if my skin is just more delicate or sensitive.
One last thing - I'm not sure what those metal pieces in the back are for (the ones resting on the shoulder blade). They don't seem to serve a purpose other than rip a few pieces of my hair off if I'm not careful. I still have to wear my hair completely out of the way (like a bun!) or else it catches every so often.
Anyway, I've tightened the strap three notches during the reception of the latest wedding, and it was much more comfortable after that. Though I'll have to wait a few weeks to test that theory out. Still, it's a beautiful strap and I get a lot of compliments on it. Well, either "Cool strap" or "You look like Laura Croft!" or something along the lines of that.
