Hey, so I decided to upgrade from combo amps, and I bought myself my first head a few days ago! Which is a Peavey tour 700 (700 watts at 4 ohms, 500 at 8 ohms). However now i'm looking at buying a cab (from Craigslist, because of budget concerns) and I'm trying to choose between two cabs. A GK Backline 410blx-II which is 400 watts at 8 ohms, and a Peavey 1810 which is 200 watts at 4 ohms. I'm wondering which is the better purchase? Keeping in mind two things: 1) I'm afraid of blowing up the Peavey cab and 2) the Peavey cab is either quite heavy but manageable (50-60 lbs, according to the guy selling it, or it's almost the same size as I am (120 lbs, according to Peavey's website somewhere which I can no longer find). If it's the latter it's probably totally unusable for me. So what should I do?
