here are my experiences - d521 - strongest rim ever, but not available as wide rim echo 06 - pish (da even go there) echo 07 - second best rim i have used for strength (behind the d521) really good rims. and fairly light try-all - why would you go there, even 8 stone towler kills try-alls. your likely to as well. dx-32 - a good rim for the price actually. i ran one for ages and took it like a man. commenting on other peoples comments... a revell rim looks like a standard catalogue rim with hexagon holes (same as a viz rim) dont do try-alls.....
