this is where i think people will have many opinions, when it comes to heavy or light bodies, i dont care. I don't beleive that should be your question, hollow bodies tend to have a bit more of a higher bite and a bit more resonance. if thats what you like then great, if you want something thats phatter and with more presence then a solid body tends to acheive this better. Although im sure there will be someone on here who would disagree with this approach.
You could take a more practical approach and if someone argues in favour of the light... "because the guitar is too heavy if your playing a 4 hours set it might hurt" all i have to say is have a WIDE strap and the heaviest guitar will be comfortable, ussually its the stap digging into your shoulder thats the problem. Leather with padding is the way forward. But i assume since your talking about strats then weight isnt the issue since they arent that heavy in the first place. For me if my guitar was too light it would feel cheap, thats just my personal preference. however I do like the tonal texture of a chambered strat, it feels a bit more resonancy which i like, Plus if you add a soundhole it could look extra bitchin!
anyways, i kind of always take the practical approach in regards to "what im gonna do with this tool, and what will i use it for?" It could be a specific sound im after, like a strat sound, or it might be a guitar that i want to sound like a humbucking rock machine. you might what your guitar to do both. I always think its best to have a use for it as apposed to just having one because its unique and special to you, however its definitely a reasons why i would buy a warmoth instead of a regular strat, but there would be more underlaying reason as to why i would have a custom made strat like having a wilkinson bridge instead of a flyod and locking nut, having an earvana nut and stuff, to me all this is more then just cosmetics, as im sure it is for most people.
anyways i feel my point is getting clouded by my rambling, im sure you'll be happy with whatever you choose :laughing7:
