I think I have a reasonable soultion to half the problem, let me know what you think...

I will buy the Bondhus 7 piece metric balldriver set: http://www3.towerhobbies.com/cgi-bin...&I=LX9123&P=ML
The set has: 1.27, 1.5, 2, 2.5, 3, 4 and 5mm sizes.

I will also buy the Bondhus 8 piece standard ball driver set: http://www3.towerhobbies.com/cgi-bin...?&I=LX9121&P=M
The set has: .050, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64 and 5/32 sizes.

Finally I will buy the Bondhus 22 piece L wrench metric and standard set: http://www3.towerhobbies.com/cgi-bin...&I=LXVCV9&P=ML
The set has: .050", 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 3/16", 7/32", 1/4", 5/16", 3/8" and 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm and 10mm sizes.

Here is the logic (let me know if I am nuts)... I will use the high grade (well as high grade as an L wrench can be) L wrenches ONLY to start a screw and do the final torquing and use the ball drivers for the rest of the wrenching. I figure that saves the ball drivers from excess wear and tear, the L's should be good enough for now to save me from buying straight hex drivers for the time being, and finally the L's come with a ton of sizes in the odd event I need something not in the ball driver kits.

Does this seem like a reasonable plan somewhere in the middle of buying a complete set of ball drivers and hex drivers...?

Finally anyone with thoughts on common nut driver sizes, brands to consider for nut drivers, and is getting a few JIS screwdrivers for the O.S. Engine screws worth it?

Thanks...
