here's what i don't like about DX's twofish clones... refer to the pictures, above...

the "real" twofish has two velcro straps that wrap around each other and compress the rubber. if the rubber spontaneously ceased to exist, you'd be left with two velcro straps holding on to each other.

the DX clones have two velcro straps that don't go through each other. in use, they pull the rubber apart.

i may be able to buy 5 of the clones for the price of one twofish, but my twofish will last 5x longer because the straps are compressing the rubber, not pulling it apart.
