Can't really say much about Full Tilts, except for all the stuff you hear about them... I tried them on and they didn't fit me because I have a wide foot with a high instep. Quality seemed really good though when trying them on.
I did infact go for the Tecnica Agent 100s which are the previous years model to the 110s, basically the same boot... Even with them my feet were too wide, but had the sides stretched out a little and put in some footbeds and now they're the best boots I've ever worn... Can ski all day without any issues... I do get some arch pain in the beginning, but that's because I have fallen arches with inflexible feet and need some time to adjust to the boots. The quality of them are really good... Have worn them for this season and have given them a bit of a beating... No problems at all.
As people have said above you need to go see a boot fitter and find out what fits you, as Full Tilts run rather slim and Tecnicas are wider... It's like comparing Full Tilts with SPKs.
