I agree, Burton Custom boards do have a really nice feel to them. I think you could get away with that board while you are still progressing. You should find it easy to tilt on edge, which is nice especially on hard pack snow and ice. It may interfere somewhat with flotation in soft stuff; also may cause toe/heel drag when tilted sharply on edge (sharp carve turns or edging on steep slopes).Also be advised, that at size 11 US boot size you are not exactly a Sasquatch. You do not need a “wide board” but rather a “mid-wide board”. I think a 251 – 257 width would suit you just fine for advanced riding.
