the MIP tips are probably the best, losi tools are a close 2nd. only complaint i have with the losi is they are a little short. i got the Losi 8-in-1 Locking Hex Wrench Kit (nice due to them chucking in most drill drivers) and the normal losi hex tools. i been wrenching with the same tools for over 5 years and still help out at the track on the screw that no one can get out. as far as nut drivers the AE are just as good as any and i think the price is good as well.
