GG's have one significant problem, though. They are screaming buggers to clean, especially if you don't do it fairly often. I have a welding brush that I use to clean between the rails but I still have to take them off every now and then and put them in a plastic bag full of oven cleaner then hit them with the garden spray (hard) the next day. Nirvana would be GG's that could go in the dishwasher!
