I deviated from Swords and Wizardry on Attribute bonuses. I didn't want to use the full +1 for every two of the d20 SRD but felt the Swords and Wizardry was too minimal. So I opted for a +1 for 3 points of attributes. This works hand and hand with the ability system that I use to resolve most non-combat actions.
For those of you use who don't have my Majestic Wilderlands supplement, the general rule is that the player has to describe what he is doing as his character. If failing has meaningful consequences then I have roll a 1d20 over a certain number. Typically a 15, 10 if it is easy, 20 if it is hard. To this roll the character can add his attribute bonus and the relevant ability bonus.
I have to stress any character can attempt any action. A cleric can lockpick, a fighter can attempt to puzzle out a magic item, a magic-user can try to bust down a door, a burglar can try to figure out a point of theology. However various classes are better at some things than others.
Also I pared down the wordage from the Swords and Wizardry original. I found the minimal description were more than adequate to explain even to a novice what the attributes represent.
I use the Lamentation of Flame Princess encumbrance system in place of tracking weight in Swords and Wizardry. I think Raggi's mechanics is simply brilliant in its simplicity and ease of use. In practice player hardly don't keep real track of it. I pay attention to the number of items they carry from time to time and it obvious when they are going to bust their weight limits. In the campaigns I ran so far, eventually the party pool their funds and either commission or buy outright a bag of holding.
