from what i read, he's tried them on.
Fulltilts are a bit overrated, they're narrow and dont offer much support.
SPK's are good, but they tend to pack out a size
Agents, well ive never worn them but ive heard good things, i hear they're also pretty light.
overall, i'd go SPK, but it comes down to what fits best, though I usually prefer a lighter boot.
If you get Full Tilts they will make you dub cork. Trust me.
