i have the hozan hook spanner and i hate it. i always have to wrap my hand in an old tshirt (the metal is uncomfortable to push very hard on, and you need to push rather hard on it!) and it slips off alot (and you can skin your knuckles on the spokes). i wish i had the pliers style. or the pauls ultimate wrench.
for a cheaper option i would get the doubled hook spanner (that has the slot).
