Hey MrWarspite, another suggestion - Harmonic and jinko recommended cutting the inside 'cup' out of 'em (the bit on yours that has the burnt spot, so the silicone isn't as close to the coil) - worked a treat for me. I used needle nosed scissors from my dissection kit, but the guys reckoned nail clippers or scissors worked, too.
can you post a picture of the finished product vapid?
