My Irideon tights are my current favorites, but I also like Tropical Riders and have recently bought my first pair of Rackerwear tights (so far, I like them a lot..but have only ridden 50 miles in them).
I use Kerrits for training rides, as I have found they do not hold up for me over the longer distances (I used a pair for a 2-day 100 last year and they were literally coming apart at the seams when I was done).
If you are looking to dissipate heat, look for a non-cotton tight as they are SO much cooler. The moisture-wicking ones are slightly more expensive but are totally worth it.
I am not personally familiar with the Crazy Legs brand you linked, but they sure look like fun!
I have 2 pair of Tuff Rider cotton Knit breeches, pull on(no snap or zipper, no velcro at the bottom, but have belt loops) knee patch. One pair is sand color, one pair Merlot. I will sell if anyone is interested. I have lost 20 lbs, and they are a bit big for me now. New, with tags. Size 32. Cost me $36 each, plus shipping. I will take $70.00, and I will ship.
