Re: Which Single Coil?
Its really up to what you want from your guitar, but you've pretty much nailed the slash thing already with the humbuckers. I prefer a true single coil in between two humbuckers, it just gives you a bigger range of tones to work with than 3 humbuckers would. I'd go with a vintage style single coil, but if you hate hum then a noiseless single coil (not a single coil sized humbucker). Its up to what you want out of those positions on the switch though really.
