"excellent complement to your other cams, packaged w/ just the sizes you want"
The cams on my trad rack are blue-red Metolius Ultralight TCUs (this product), yellow-black Metolius Master cams, and #.5 to #5 BD Camalots doubled up #1 to #3. The 3-lobe design of the TCUs makes them a key piece to a rack because they will fit perfectly into some cracks that the 4-lobe designs will leave you praying for your life. The reverse is also true too, so variety is often your friend. I find the TCUs to be comfortable to place and retrieve, and I feel confident climbing above them.I really love all the cams on my rack, and the way they work together to provide a wide range of placements. I would highly recommend having this set of TCU's on your rack.
"Tough as nails, but sometimes tougher than the rock..."
These cams are tough as nails - I dropped one 60m and it held a lead fall a few months later. My whole set rusted a at the heads when they got a bit wet, but are still holding up nicely. While stronger than Metolius four lobed cams of the same size, I was warned that four lobed cams would be more solid in cracks in which you would place cams of this size because of the greater rock contact. I blew the rock next to the number 1 TCU in one placement, a four lobed cam might have held -- so strength is not everything. Bar the rusting, I am pretty happy with them -- quick and easy to place when sketching out over thin ground!
Buy these instead of BD cams smaller than .75; they're lighter and make you feel just as good when placing them. For some reason the TCUs are more confidence inspiring than the larger Power Cams, I don't know why. The expansion range is not as good as Camalots.
These cams are great, every time I place one of these I feel really great about it. So far the blue a the orange have saved my life. The only downfalls are that range on the smaller sizes is very low and will jam easily if placed to tight, also since there is only one cam lobe on one side they turn very easily, which is both good and bad. Just Make sure you know what position your cam is in when your above it.
I have been using the TCU's (#1-4) for a year now and they are a perfect complement to my set of Black Diamond C4's #.5-4. There design allows for perfect placements where nothing else will hold. My first falling experience was on the smallest blue TCU that was placed in a shallow pocket with only 2 cam lobes making contact and it held, through 3 falls, until i was able to send the route. I have also found that their design allows for quick placements which is awesome for those OMG moments. For the price there is no justification for not having a set of these on your rack, period. got it son?
Got these guys to compliment my C4's and C3's...they fit where nothing else does and makes a bomber placement, especially the yellow IMHO. I took my first fall on the yellow and it held like a 6 inch bolt. I love the light weight and trigger action. The only downside, which is not a performance issue, is the useless color dots. If you're relying on these to justify a placement, you shouldn't be leading. Great cams.
These tcu's have a great slim profile design that allows these cams to be placed in very odd shaped pockets, seems, and odd shaped cracks. I recommend these as a staple for a North Carolina style trad rack. Also it is a good idea to look into getting the entire 00-4 set in order to really protect the route.
They just FIT! Some aren't into the trigger design on Metolius Cams, and while I like the C3's trigger assembly better, the actual placements that you get with these is superb. I feel very comfortable climbing above these babies.
