By myself, I like listening to the timbre of the timber. I have the EQ on my rig dialed in. So, tone isn't an issue. I also have a 350w combo but use it primarily as a guitar amp. If I need to hear myself amplified, I have an effects system I can plug headphones into. In a band practice setting, I use the rig. I think it makes sense to practice using the same tone that I would live. That way you know what you've got, no surprises.
