dome it is then!
as for the nail, ti nail better than glass and quartz?
its all preference but i know that glass nails have a tendency to break when they get too hot which is why some people use ti but i think titantinum has a weird taste? this is just what ive read ive only ever used glass and it works great.
id say, from personal experience... go with the ti nail. i bought a dome setup that came with 2 glass nails at my local headshop... i used the glass nail for about a day before i walked right back in that bitch to get the ti nail. nothing against glass nails, but i know they break... a lot! i only got the ti nail just cause .. ive had it for a year now... good investment..
