I have two firm beliefs about solidbody electric guitars. Well, more like fifty, but two pertinent here.
1) All else being equal, you should play the biggest heaviest neck you can stand, because it will sound better. This is not so important if you need a Death Metal pedal plugged into a Triple Rectifier to get "your" sound.
2) Balance between components matters too. A huge heavy neck on a Paulownia Strat body with .008's and a two-spring vibrato may not work great, and that bridge and springs on a 13-lb. hippie sandwich body might not work either. Balance of density and tension and such is as important as balance of weight, as I have had light guitars that just would not do a damn thing till strung with at least .011's (Gleamo the Aluminum Tele - light but stiff, oh aluminum is stiff) and heavyweight guitars that thrived with .009's. And the amp vs. woodiness is largely, surprise, determined by the amp & stages of drive. Anything can howl if you juice it enough.
