You will have to buy and cut skins yourself for the R2 122, however that shouldn't be a huge problem as their dimensions (142-122-132) aren't too outlandish. Two brands mentioned above were G3 and BlackDiamond. Out of the two for the r2 122 I think prephaps G3 maybe a better choice, due to the size of the r2 122's tip. Due to the adjustable nature of the tip connecters on the G3, I would pick a pair of G3s over BDs, as with BDs you may need to purche an XWide tip loop. As for size taking into consideration the dimension either a 130Long or 140Long from G3 would suit, depending on how much coverage you think you need.
Hope this helps, Joey
Nice repley Dirty.Harry ... The tracker is infact just Atomic's rebrand of the Guardian. OP Scott also does a rebrand of the Guardian called the Scott BC Guardian. As for a comprehensive review, Blister have done one http://tinyurl.com/cpmsvbs, definately worth a look a good read.
