However if you have the money for cams forgo the hexes. I have finally completed a set of cams. I did lots of pondering over camalots and friends and settled on friends for a few reasons. First I like that the stem wire is fully visible for inspection unlike the camalot. I know camalots have more range but having pieces seemes more important, and to buy more camalots to make up for those is more expensive.
Third friends are lighter and seem easier to place.
One gripe for the salesman about the fact that camalots can be pasive as well as active. Further note the only bad thing about friends is the limited range of the set. My future purchase in to get some of the larger camalots to complete my cams for leading. It is important that you research what you buy on your own. The above statements are not a guarantee that the gear will be any good for you.
