Well I think the Linkcam will be my next bit of trad gear to buy. Quite honestly I have never been a big fan of Omega Pacific. I have thought of them as being on the "bargin bin" end of climbing gear. Don't trust your life to the bargin bin.
I have talked to a few people who use OP and don't have any major problems.
So...why would I think of buying the Linkcam if I don't like OP. The Linkcam does have a bit of a niche and it is the vast range the cam has. The smaller has a range of 0.83 to 2.10 inches and the larger has a range of 0.96 to 2.51 inches. That is about the same range a about 4 consecutive cams of standard types.
This is good for two situations. First is the sphincter twitcher. When you have a less than ideal grip and you have one quick chance for a placement, you don't want to fumble with the correct size. The other situation is when you are on a long trad route and you have used up most your cams. This one should fit just about anything.
Then there is the most obvious reason...I like new toys. But it that reason enough, the thing cost about 100$ a pop!!!
