Atomik Climbing Holds recently developed a line of holds specifically for DRY ICE Tools, and they are spectacular! Below is a brief review of the 40 holds they've developed, why they are awesome, and links to where to get them.
There are 5 sets in the proton-based series.
15 SUPER SMALL $47.96
These are by far the most technical holds in the line. Climbers must deftly focus on body positioning and steady strap placement or, like any placement outdoors, the placement may blow of the hold. Truly the realm of a technical master, these holds put the mixed climber's skills to the test.
ACH also cleverly designed in a unique feature to this line: Many of the holds have side 'protons' that help to lock the strap of the DRY ICE Tool in place when loaded in a specific direction.
10 SUPER SMALL $15.26
Not really a variation of the proton line, these holds are easily some of the best holds for DRY ICE Tools on the market today. This is because they are small, just-positive-enough micro horns that come in a pack of 10. So with only 2 sets of these, you have a 60ft (18m) route. At only $15.26 per set, these are such an incredible steal.
5 MEDIUM PROTONS $36.90
Increasing in size, these are holds can be forgiving on the new ice climber. Like the 15 Super Small, some of the holds in this set of 5 have side protons that help lock in the strap for interesting and secure placements. They average 3-5 in in diameter with about 2 in of positivity, making for easily loop-able placements.
For more of a challenge, use these holds on steeper terrain and use only the side protons. By setting these holds on steep routes, you really get two sets of holds for the price of one: One set for easier routes, and one for steep and technical climbing.
5 LARGE PROTONS $47.60
Just a small percentage larger than the 5 Medium Protons, this set shares many of the same features. Set on vertical to off-vertical terrain, these are very simple to use with the DRY ICE Tools. Set on steep terrain the Large Protons will test technical skills by using only a single proton.
5 XL PROTONS $75.00
As big as is reasonable to use with DRY ICE Tools, the XL Protons are mega-fun in a mega-size. The single large proton is perfect for the strap on core-working super steep terrain. Think overhanging roof lines, challenging DRY ICE boulder problems, underclings, as well as in opposition.
