100w heads do give more headroom with cleans. When I drop mine to half power the cleans break up easier.
I did think that my amp which is 120w is ott for home use but with an attenuator or in my amps case even without it will still sound great at low volumes. It gives me all the options i need with out having loads of different amps. That was what the engineers had in mind when they designed it.
If you ever fancy an attenuator Aliean, have a look at the Koch one, it has loads of options for recording. Line outs, XLR out, ground loop lift, 1x12, 4x12 simulators with open or closed mic.
I'd go with what the others said about not being too hard on your playing. If you can find some others to jam with this will bring your playing on in leaps and bounds. Then you can crank it up and get some harmonic feedback going. Your think you've died and gone to heaven! Jamming in itself is just so rewarding and great to do. I'm in a studio this weekend with a sax player,another guitarist, a superb bass player and new drummer. Have a look on Gumtree.com for people to hook up with.
