Groupset Recommendations?

Modern hubs are 130mm, the rear spacing of a 90's frame is possibly going to be 126mm, not a big issue but something to bear in mind

thanks for the info, I know there are 126 and 130 spacing, can I assume that the 130 spacing is for more gears 9/10 speed and 126 for 8 speed?

If you're new to gears it might be worth copping a feel of the different hood styles to see what suits before you lay any cash down.

thanks, this is part of the original question as I understand it can make quite a difference. Does anyone know if there is a general rule of thumb for which hoods are considered good, or is it all down to some people find Shimano better, some people Campag? or does it depend on individual hand shape / riding position and style?
