Well, its worse than Ice Wall in that it costs $1 more to rez. But "Slightly worse than ice wall" is not exactly a problem, ice wall is awesome.
Wraparound costs the same amount for Corroder to break as Ice Wall and Himitsu. Theyre all $1.
How much does Crypsis cost to break them? It costs Crypsis $2+* for ice wall, $3+* for Himitsu, and $8+* for Wraparound.
Its much harder for Atman to break it (7 str!) than it is for Atman to break the others.
Against all the relevant breakers, its way better than the alternative small barriers. Ice Wall is $1 cheaper, and advanceable. Other than that, this one is the best.
