Is there any way to "feel" what the right torque might be for a square taper crankset? I don't have a torque wrench. Or is "tight" good enough? I have a short little 6" ratcheting wrench that I used.

The article on SB's site says that you should not retighten the crank bolts if they loosen over time... so what do I do if I find that my crank bolts have loosened?
