I'm caught between a rock and a hard place of preferring the lower gearing the 42 offers over the 40 but it does start to become a bit "gappy" on the bigger rings so interested in people's opinions generally and also if anyone else has done similar and if you'd choose the same again or a different cassette for either of the reasons I've mentioned..

So there is a 39t max on the 105, correct? That can be fudged and whatnot since Shimano is conservative, but a 32/48 mated to an 11-42 would mean a total wrap of 47. That isnt too much? I guess never going into the 32-11 combo will help too.
