5 XL Mudplate Jugs

These are great as hands on a roof. Also they are thicker than most roof jugs, so there is more room between the wall and where you grab it, so you can even use them as good roof feet.

They are called "roof jugs," after all.  That in mind, I feel like my review is a bit limited since I have used them exclusively on a 45 deg wall.  At 45, they are still very, very, very positive.  The exterior is very unique and beautiful; the interior (where the fingers touch) is basic bucket without a unique feel).  These jugs would still be positive at 70 deg.  When you throw to these holds on a 45, your hand grabs them from a different angle than you would is approaching them on a steeper wall.  One of the holds can be a bit sharp on dynos from 45; that wouldn't be an issue on true roofs.   Atomik has many great options for 45 deg walls; however, this set would not be my first choice at that angel.  If I ever build a 70 deg wall, I'm sure they will excel there.  
TL;DR.  Likely best on 70 deg to horizontal.  Not my fav at 45 deg.

The mudplate design is a cool texture and adds a nice look to the home wall assortment. I have a couple on a 45 degree overhang section and the rest on the ceiling. On the ceiling they are great pulls with plenty of grip.

I rarely see this kind of design at gyms.  It's not going to look or feel as bread-and-butter as other jugs, so it's definitely worth considering.  I'm a V3 climber and use these on a 30 degree wall, and for me these feel great.

Best hold set in the mud plate series.  Feels a lot like holds in chossy steep terrain outside yet is still helpful as a training tool.  Big enough to be put on the steepest of walls.
