Just from observations of fighting jhun with no acc, or as rdm/bst with about 20 acc, your percentage hits would be around 70% for most T-low VT mobs.
That's not so bad when you consider that ridill gives around 2.01 hits per round with brutal (actually I think it's less, but I have yet to see any actual evidence if it is 1*.25 + 2*.5 + 3*.25 or 1*.5 +2*.25 + 3*.25, so I'll choose the highest one).
With A- skill and 50 acc your going to have around 90% acc on the same mobs.
So for a bst maneater/ridill you are looking at 1.05 * .9 + 2.01 * .7 =2.35 hits per round.
For maneater/temp you are looking at 1.05* .9 + 1.55* .9 = 2.34.
Now this isn't really fair since ridill has lower delay if we look at tp per 100 delay of each weapon we have around 31.6 tp per 100 delay for the man/ridill combo and 31.3 tp per 1000 delay for the man/temp combo.
So, supprisingly if ridill really has an average of 2 attacks per round, then it's tp gain is the same as temp. However, dot would be considerably better on the side of man/temp since the attack difference between swords and axes still does exist. Ridill would also lower expected WS damage.
Temp/Ridill would be an interesting combo though, but I would be much happier with Guttler/Temp
