Minor quibble perhaps, but with the 'Replace many +1 magical weapons with Fine ones -> Fine weapons are immune to the iron crisis' component installed, it looks like 'Excellent' long bows have a +1 bonus to damage when the standard +1 versions do not, making it identical as far as stats to Excellent Composite long bows (other than not requiring 18 STR and being 50 gp cheaper in spite of greater utility as a result of not requiring 18STR). Aside from variance from the original versions, it seems like it contradicts the whole idea that the composite version does more damage due to greater pull/requiring greater STR.
[edit, I suppose if the excellent versions of +1 weapons are by design intended to retain the +1 to damage (it seems they are), it's really the other way around, excellent compound longbows missing an additional +1 to dmg rather than excellent longbows getting an extra +1]
I'm also experiencing fine/excellent weapons breaking during iron crisis even though the above is installed, though that may be due to my installing this particular component quite later on, apart from the rest of SCS components.
