i gotta say the straight flip over ones have been the best for me in general,

flex heads are too bulky and flex when you try get the end on unless you hold them,

the flex lock ones are expensive and fiddly to use and the ratchet reverse lever on

angled ones is something to get caught when your working. depends on what type of

application you use them for though :D the flex head ones are literally rachet crows foot

spanners in a sense for difficult to reach areas but you can't crack or do up bolts in the

crows foot position though.

 

i use the trade tools force flip over ones, come in a comprehensive set with cheap single replacements

and are really cheap with a lifetime warranty.

 

i think its about $100 for 8mm to 19mm ( includes most sizes )

and about $160 for 10mm to 24mm?? (includes most sizes)

 

definately worth the money to have a set whatever the brand / type though!

I didnt really think about the fact that most japanese stuff is all metric headed bolts and nuts, I kept wondering why everyone only had metric sets :D
